Is this the first blender release where you can change the working color space? I thought that you could in previous versions but it caused issues with some nodes.

Now I want to look into it more, but I'd imagine that "Blackbody" and sky generation nodes might still assume a linear sRGB working space.

> Now I want to look into it more, but I'd imagine that "Blackbody" and sky generation nodes might still assume a linear sRGB working space.

Since people are always asking for “real world examples”, I have to point out this is a great place to use an agent like Claude Code or Codex. Clone the source, have your coding assistant run its /init routine to survey the codebase and get a lay of the land, then turn “thinking” to max and ask it “Do the Blackbody attribute for volumes and the sky generation nodes still expect to be working in linear sRGB? Or do they take advantage of the new ACES 2.0 support? Analyze the codebase, give examples and cite lines of code to support your conclusions.”

The best part: I’m probably wrong to assert that linear sRGB and ACES 2.0 are some sort of binary, but that’s exactly the kind of knowledge a good coding agent will have, and it will likely fold an explanation of the proper mental model into its response.

why ACES and not something like P3?
1220512064
20h ago
1 reply
Display P3 (distinct from cinema display P3, because names are hard ig) is used as a render target color space. ACES (and its internal color spaces) are designed as working spaces.

If you make a color space for a display, the intent is that you can (eventually) get a display which can display all those colors. However, given the shape of the human color gamut, you can't choose three color primaries which form a triangle which precisely contain the human color gamut. With a display color space, you want to pick primaries which live inside the gamut; else you'd be wasting your display on colors that people can't see. For a working space, you want to pick primaries which contain the entire human color gamut, including some colors people can't see (since it can be helpful when rendering to avoid clipping).

Beyond that, ACES isn't just one color space; it's several. ACEScg, for example, uses a linear transfer function, and is useful for rendering applications. A colorist would likely transform ACEScg colors into ACEScc (or something of that ilk) so that the response curves of their coloring tools are closer to what they're used it (i.e. they have a logarithmic response similar to old-fashioned analogue telecine machines).

no monitor uses ACES so it always needs to be converted to P3 to even see what you're doing right?

or you are saying if there is some intermediate transform that makes color go beyond P3 it will get clipped? then I understand...

adgjlsfhk1
19h ago
The key point is that your ray tracing color space and your display color space don't need to be the same thing. Even if your monitor only displays SRGB colors, it still can be useful to have more pure primaries in your rendering system.

> or you are saying if there is some intermediate transform that makes color go beyond P3 it will get clipped?

Exactly! The conversion between ACES (or any working color space) and the display color space benefits from manual tweaking to preserve artistic intent.

Uehreka
16h ago
Yeah, like, let’s say that in your compositing workflow you increase exposure then decrease brightness. If your working color space is too small, your highlights will clip when you increase exposure, then all land flat at the same level when you decrease brightness. If your working space is bigger than the gamut people can see, but your last step is to tone map into Display P3, you’ll appreciate the non-clipped highlights, even if your eyes could never comprehend what they looked like in the post-exposure-boost-pre-brightness-drop phase of the pipeline.

If AI is at the point where it is exactly as capable of your average junior 3D professional in 10 years, it will probably have automated a ton (double digit percentage?) of current jobs such that nothing is safe. There's a lot of complexity, it's fairly long time horizon, it's very visually detailed, it's creative and subjective, and there's not a lot of easily accessible high quality training data.

It's like 2D art with more complexity and less training data. Non-AI 2D art and animation tools haven't been made irrelevant yet, and don't look like they will be soon.

Directors spend a LOT of effort trying to keep continuity and that's the weakest part of AI.

What blender and other CGI software gets for free is continuity. The 3D model does not change without explicitly making it change.

Until we get AI which can regenerate the same model from one scene to the next, the use of AI in CGI will be severely limited.

john_minsk
14h ago
That's exactly what I think will happen. 3D is endgame for AI. 3D models are deterministic objects that provide continuity, while AI does non-deterministic abstract generation(thinking) + plans action plan for these 3d models.

Recent news on major AI scientists starting "world AI" companies confirm this trend.

So 3D soon will become a very important tech even compared to today.

I design projections for independent theatre in Baltimore. I use AI in my workflows where it can help me and won’t compromise on the quality of what I’m making. I frequently use AI to upscale crappy footage, to interpolate frames in existing video (for artistic purposes, never with documentary archival stuff) and very occasionally to create wholesale clips in situations where video models can do what I need.

I recently used WAN to generate a looping clip of clouds moving quickly, something that’s difficult to do in CGI and impossible to capture live action. It worked out because I didn’t have specific demands other than what I just said, and I wasn’t asking for anything too obscure.

At this point, I expect the quality of local video models (the only kind I’m willing to work with professionally) to go up, but prompt adherence seems like a tough nut to crack, which makes me think it may be a while before we have prosumer models that can replace what I do in Blender.

You will still need the tool but the interface to it may start to change.

A lot of the editing functions for 3D art play some role in achieving verisimilitude in the result - that it looks and feels believably like some source reference, in terms of shapes, materials, lights, motion and so on. For the parts of that where what you really want to say is "just configure A to be more like B", prompting and generative approaches can add a lot of value. It will be a great boost to new CG users and allow one person to feel confident in taking on more steps in the pipeline. Every 3D package today resembles an astronaut control panel because there is too much to configure and the actual productions tend to divvy up the work into specialty roles where it can become someone's job to know the way to handle a particular step.

However, the actual underlying pipeline can't be shortcut: the consistency built by traditional CG algorithms is the source of the value within CG, and still needs human attention to be directed towards some purpose. So we end up in equilibriums where the budget for a production can still go towards crafting an expensive new look, but the work itself is more targeted - decorating the interior instead of architecting the whole house.

As someone who's actually used Blender for small video projects, I'm fairly confident you'll still need this type of tool even with AI assistance doing some of the work in it, especially for at least the next 10 years.

AI coding agents didn't make IDEs obsolete. They just added plugins to some existing IDEs and spawned a few new ones.

I've been using blender since at least 2010; it's so exciting to see how much progress it's making.

I'm very excited to see the addition of structs and closures/higher-order functions to blender nodes! (I've also glanced at the shader compiler they're using to lower it to GLSL; neat stuff!) Not only is this practically going to be helpful, the PL researcher in me is tickled by seeing these features get added to a graphical programming language.

If you haven't heard of Blender before, or if you think AI will replace all the work done in it, fair enough. But I'd still strongly suggest looking into what it is and how it works.

I actually did the same thing so that I could figure out how to lay out my workshop!

What I'd do is:

- Spreadsheet workbench --> Create spreadsheet (name it "measurements"). (This is optional)

- Switch to Part design workbench --> Create body (name it "layout") --> select XY plane --> Create sketch --> Create Polyline

- Zoom out, start drawing the rooms in your house, approximately to scale.

- Before going into too much detail, add a dimension (select line --> "Constrain Distance") to the first line you draw, so that you can do the rest of your drawing approximately to scale. Then the general shape won't get messed up when you add dimensions to everything else.

- (If you have a photo or picture, you can import that to sketch over).

- Add constraints to match your room measurements, mostly vertical or horizontal distance constraints. Be careful not to overconstrain the sketch. (You can put the measurements directly into the sketch constraints, or you can put them into the top-level spreadsheet, create an alias for each cells, and then set the dimensions to reference those cells).

- Once the rooms are drawn, close the sketch and create a new sketch on the xy plane called "furniture".

- Draw some rectangles for your sofas / tables / etc, delete any horizontal and vertical constraints that get automatically added, and instead apply perpendicularity constraints. Dimension your rectangles using only the "constrain distance" tool. Now you can drag them around the room and rotate them freely.

- If you want to make 3D models for these too, create new Part Design bodies for each room and each piece of furniture, create a shape binder referencing the master sketches in the Layout body, and then extrude the sketches using the "Pad" operation.

That's about as much tutorial as it makes sense to pack into a HN comment. If you give it a try, I hope it works out for you!

There are excellent tutorials on youtube. Spending a couple of hours doing these will allow you to hit the ground running.

FreeCad is rapidly evolving and quite a few tutorials are already using the v1.1 dev builds. Pay attention to the version used in tutorials as you can run into trouble following them if you are on an older release.

Approached it with the same attitude at the same time, after 10 minutes decided to view some basic tutorial (for an earlier release) that made things clear and I could continue basic tinkering on my own.

I tried FreeCAD and the user interface is so unintuitive and things just have constraints that block you from doing the most basic things from the get-go that I just gave up in 10m, like sibling. SCAD is scripted/programmer CAD, I like the concept and have used for a few things but it's quite a learning curve to do anything more than a cube with some funny edges!

OpenSCAD is great, I’ve made some very complex stuff in it that would be hard to make even in professional tools like Fusion. For some reason the main OpenSCAD releases don’t seem to get updated (the current version on the site is 2021.x). The nightly builds are great though, and I recommend getting one and turning on the Manifold backend since it is MUCH faster than the default CGAL one.

This is in contrasti to the example the parent comment brought up, and the one I added: Blender and KiCad do not have this concern; there are free (Or you could say inexpensive) high quality tools in their spaces. This is notably not the case for traditional CAD.

During COVID I learnt Blender for 3D modelling. It is still my go to.

Many people complain about it being a mesh editor but it works for me. The sheer variety of tooling and flexibility in Blender is insane, and that's before you get to the world of add-ons.

I want to learn Geometry nodes and object generation as I think they will address a lot of the "parametric" crowd concerns. This v5 is meant to be a big step in ease of use of this.

Also, I'm not sure if the different tooling lets me see all the flaws of online "parametric" models, or whether I'm being pedantic. They get frustrating. I have Gordon-Ramsay-screamed "How can you fuck up a circle!".

jwagenet

In MCAD, “parametric” does not mean a high level part or feature is driven by editable parameters or procedurally generated features. Parametric refers to the underlying storage format representing part features in a parametric way rather than as a mesh. Mesh formats like stl cannot represent a circle by its position and radius, while a parametric format like step can. This distinction is more akin to raster (bmp) vs vector (svg) graphics. Both can be generated procedurally by “parameters”, but only with svg can sub-features be faithfully extracted or transformed.

Sorry, separate point:

>Mesh formats like stl cannot represent a circle by its position and radius, while a parametric format like step can.

This is where I think the Geometry nodes can help. A node (function) can be used to represent the circle with inputs and outputs set or changed as required.[0]

I have some understanding of "parametric" vs "mesh". I looked it up when I saw so many people going on about it.

Maybe it is the export or something. I run the 3D toolbox and often models are not manifold.

I see things like two circles in slightly different positions but both are connected in different ways to the surrounding "single" instance model. Things like this mean you end up with "infinitely small volumes" like a klein bottle with infinitely thin walls. There is no fully enclosed "volume" and so mathematically there is "nothing to 3D print".

As a model this makes no sense to do, and so it irks me.

But clearly the slicer software doesn't care or autocorrects and people make their 3D print happen just fine.

Depends if your goal is artistic or functional. Blender is good if you are trying to make character models, etc. It's not great when you are trying to make a part that has to fit something in the real world and after printing you discover one step half way through needs to be 1mm shorter.

It does take a different set of skills to regular CAD, but I haven't found it that bad for simple 3D printed models that need to be dimensionally accurate.

I haven't tried any of the cad plugins for blender, but I'm not sure how you would retroactively change dimensions in blender. It's usually simple enough to create features to a certain size, but if you need to change them later it becomes significantly difficult.

If I put some holes in something that are 1mm from the edge, but then I print it and see it doesn't line up and needs to be 1.5mm, in Fusion I can just change one number and it all updates. Doing the same thing in blender would likely be very difficult.

While it's a pain to learn and requires some plugins (addons) for basic ergonomics, FreeCAD absolutely works for parametric CAD modeling. YMMV depending on the project and complexity, it does the trick for laser cutting, bending and 3D printing.

It suffers from too many "workbenches," some of which appear to be redundant or dated.

And it presents nonsensical problems, like offering to create a sketch on the face of an object and then complaining that the sketch doesn't belong to any object. So you have to manually drag it under the object in the treeview. So gallingly DUMB.

Despite all that, I will wrestle with its ineptitude before giving Autodesk a penny.

Same, but I don't think it's possible without a large and sustained investment into a free geometric modelling kernel, which can probably be only done by a government.

Parasolid is powering practically every major CAD system. Its development started in 1986 and it's still actively developed. The amount of effort that goes into those things is immense (39 years of commercial development!) and I don't believe it can be done pro-bono in someone's spare time. What's worse, with this kind of software there is no "graceful degradation": while something like a MIP solver can be useful even if it's quite a bit slower than Gurobi, a kernel that can't model complex lofts and fillets is not particularly useful.

3D CAD is much harder than Blender and less amenable to open source development.

I'm very skeptical that one person can make a dent. Paging through the releases, they seem to focus on constructive solid geometry and code-driven shape generation, which I believe is a dead end.

The tricky bit is having a G2 fillet that intersects a complex shape built from surface patches and thickened, with both projected into a new sketch, and keeping the workflow sane if I go and adjust the original fillet. I hope one day we'll see a free (as in speech) kernel that can enable that, until then it's just Parasolid, sadly.

Can you help me understand why this problem is so hard?

CoreformGreg
17h ago
The other reply is really good. To add to that, the intersection of two bi-cubic Bezier patches (each being but one part of a cubic B-spline surface) is an implicit equation of degree 18^2=324. This simply cannot be implemented exactly in a geometry kernel and thus must be approximated. How do you want to approximate this? If you choose trimming (the industry standard) now you have to handle gaps in your geometry. If you choose remapping into a watertight spline, you need to solve a constraint system that is NP-hard. If you choose reparameterizing… well, see nVariate’s watertight Boolean technique (disclaimer: I once sponsored a project with nVariate).

Now, generally speaking, in a CAD model most surfaces will be “analytic” (plane, torus, conical, arc, line, etc). But whenever some complex surface that joins these surfaces is required, (NUR)B-splines are the principal technique for “covering” the gap.

dgroshev
19h ago
The way modern CAD systems work is by having a tree of features/actions that is then used to construct an analytical representation of a 3D object. The features/actions can rely on "sketches" (2D drawings that are coupled with a real time geometric constraint solver) and can be "projected" into sketches, creating new reference lines, that can then be used by the sketch constrain solver, generating a sketch that can be used for more 3D features.

This is already complex and fiddly enough. Just having a stable 2D drawing environment that uses a constraint solver but also behaves predictably and doesn't run into numerical instability issues is already an achievement. You don't want a spline blowing up while the user is applying constraints one by one! And yet it's trivial compared to the rest of the problem.

Having 3D features analytically (not numerically!) interacting with each other means someone needs to write code that handles the interactions. When I click on a corner and apply a G2 fillet to it, it means that there's now a new 3D surface where every section is a spline with at least 4 control points. When I then intersect that corner with a sphere, the geometric kernel must be able to analytically represent the resulting surface (intersecting that spline-profiled surface with a sphere). If I project that surface into a sketch, the kernel needs to represent its outline from an arbitrary angle — again, analytically. Naturally, there is an explosion of special cases: that sphere might either intersect the fillet, just touch it (with a single contact point), or not touch it at all, maybe after I made some edits to the earlier features.

Blender at its core is comparatively trivial. Polygons are just clumps of points, they can be operated on numerically. CAD is hell.

Geometric modelling tends to need a lot of detailed work for two main reasons.

Firstly, you probably have a variety of analytic shapes to represent — things like lines and circles in 2D or cubes and spheres in 3D. Even seemingly simple questions, like whether two such shapes intersect or not, can require a significant amount of logic to calculate the answer. That logic will often be specific to the exact combination of shapes you have, because the number of freedoms and nature of any symmetries in the shapes you’re working with can mean you would use completely different algorithms for superficially similar situations.

Secondly, while you’re probably going to implement a lot of analytic calculations, in realistic models you’re probably going to end up using numerical methods as well. That can be because you need to work with geometry like Bézier curves or NURBS surfaces that has many freedoms. It can be because even if you start with convenient analytic shapes, new geometry that you derive from those shapes, for example by offsetting a single shape or by combining details from multiple shapes as in constructive solid geometry, won’t in general have an analytic shape itself.

By the time you allow for the numerous different types of constraint that you might want to enforce between different types of geometry and the numerous different ways you can construct new geometry from geometry you already have, the scale of the problem explodes. And on top of that, almost everything you do is going to have numerical sensitivity issues, and all but the simplest algorithms are going to need detailed, careful analysis to make sure you really have covered all the possibilities. In this field, “edge case” and “corner case” are literal terms and not just figures of speech!

To give a practical example, without looking up how to do it, could you confidently calculate whether two arbitrary cuboids are completely separate or they touch or intersect somewhere? As another example, given an arbitrary parametric surface, a sphere in a position just resting on that surface, and the constraint that the surface of the sphere must remain tangent to the parametric surface without intersecting it anywhere, how would you calculate the path the centre of the sphere will follow if you introduce gravity to start the sphere rolling in a certain direction along the surface?

These are relatively simple problems in the field, but each already has some subtlety that leaves the “obvious” solutions incomplete. Solve a few thousand problems like that, each unique and with its own calculation strategy, and now you’re starting to get a practically useful geometric modelling system. (You’ve also probably had a team of dozens of mathematicians and developers working on it for decades.)

Probably requires something that is almost there then a sponsor(s) to throw in developers or funding to get the rest of the way. On the EDA side CERN did a lot to lift Kicad to the point of being a credible alternative that could breakthrough like Blender. Both those projects are over 30 years old and for a lot of that time were dismissed as too difficult to use or lacking in features. FreeCAD is only 23 years old. I don't know what the code base is like but if a large org put a couple of good devs into it for a few years who knows.

Management just reacts to environments created by governments. When ZIRP was around money was very easy to get hold of - too easy. Now it's really hard because businesses have to beat government bond interest rates, which are guaranteed, to get debt/investment.

Your premise is wrong. It's impossible to leach off something that is freely given. This is like being angry because people don't all tip a street performer. The deal is it's free.

The problem with FreeCAD and every other free/open source MCAD project of note is the Open Cascade kernel they are built on. While Open Cascade is fairly mature, it has dealbreaker issues in a few key areas: fillets cannot consume connected faces and may fail for a number of other reasons, cylindrical and spherical faces require seams which often cause issues with boolean operations, and shapes like helixes are also often troublesome.

Something that I've daydreamed of in the past is making a new constructive solid geometry "kernel" around which a CAD application could be wrapped based on projective geometric algebra (PGA).

The algorithms it enables are fundamentally more capable and robust than traditional kernels based on linear algebra (vectors and matrices). You can do really fancy things like interpolating in space and time robustly, find extrema in high-dimensional phase spaces, etc...

This could potentially allow straightforward and robust solvers for kinematics, optimal shape finding, etc...

Every few decades there's a "step change" where some new algorithm or programming paradigm sweeps away the old approach because suddenly a hobbyist can do the same thing solo that took dozens of developers a decade in the past. I suspect (but cannot prove) that PGA is one of those things.

You may be interested in CAD Sketcher: https://www.cadsketcher.com/

You're on point that there's a tremendous amount of money captures by Autodesk for CAD software that could be better directed at the open source community instead.

Software like OpenSCAD and FreeCAD are obviously not suitable for much commercial work, and have very irritating limitations for hobbyist work, in my mind a big part of that is the UI and Blender has a good and established UI at this point so I'd love to see the open source CAD that provides an alternative to vendor lock in come from a Blender add-on instead of a separate program.

I am no expert but as I understand it the primary difficulty with developing good alternatives to commercial CAD software lie in the development of an effective geometric kernel.

It seems to me that if a developer of an opensource CAD program develops it as a Blender add-on they can effectively outsource the remainder of the development efforts to the Blender community while focus can be made on the CAD kernel itself.

I did a lot of parametric 3D CAD work in college as a MechE student, and switched to webdev after graduating. Recently, I had a hobby project that would have involved dusting off my CAD skills, and was bummed to find that there wasn't any software readily available that allowed me to lean on muscle memory I had built up using Inventor/Creo/SolidWorks/Unigraphics.

A viable OSS alternative, particularly one that prioritizes simplicity and being a gentle on-ramp for hobbyists, would be fantastic.

It wouldn't need (and I would argue shouldn't attempt) to compete with the big for-profit outfits to be useful either. Offering a simplified UX for the most-used features of the pro software would have a ton of utility, while also being a great place to build the foundational skills you need in order to master the more complex stuff.

Furthermore, a project with the mission of complementing the pro tools rather than replacing them would probably be far more likely to succeed, IMO. As long as projects could be exported to variety of formats and brought into some other software when a specific use-case arises, you'd have all your bases covered.

FreeCAD is still in active development and there was a major release (1.0) recently. There will be a feature freeze soon where the devs will focus primarily on stability and eliminating bugs.

That said, I use FC as my main CAD driver and, not only tolerate it, but enjoy using it. I had to watch several hours of introductory videos to get the hang of things initially, but now I'm quite fast and proficient.

The initial pains and common complaints about UI and such, are basically non-issues for me now and when I model, my cognitive energy is basically devoted to the design problem itself rather than issues with UI or the behavior of the software.

It's necessary to put the time into learning it, but it's worth it.

"first class open source kernel"

Speaking with over a decade of experience as a developer in industrial CAD (but still just one random guys point of view only). The question _isn't_ about the availability of a 3D kernel.

3D kernel is not the "moat".

You can cross that with money.

You can purchase a ACIS or Parasolid and you are off to the races. Or even use OpenCascade if you know what you are doing.

The more interesting question is: Ok hotshot, you have a 3D kernel, 10M of investor money (or equivalent resources).

What's your next move? What industry are you going to conquer? What are the problems you are going to solve better than the current tools do?

What's the value you provide to the users except price?

What are you going to do better than the incumbent softwares in relevant specific design industries?

Which industry is your go-to-market?

Etc etc.

The programmer's view is "I will build a CAD". The industrial user on the other hand does _NOT_ want a "general CAD software".

They want a tool with a specific, trainable workflow for their specific industrial use case.

So "if you build it and they will come" will require speaking to a specific engineering/designer audience.

You can of course build a generic tool (it's all watertight manifolds in the end) but the success in the market depends on the usual story about market forces. What's your go to market/beached. Does it enable you to move to other markets? And the answer usually is - NO. You need to build the market share in _each_ domain separately.

Blender is really an amazing case study of open source software. Apart from the Linux kernel and web browsers/tools, it is perhaps the only open source software that managed to beat all the commercial software in its niche. It has rendered Maya nearly obsolete.

Meanwhile, in other niches, Microsoft Office still beats open source office suites like LibreOffice; Photoshop isn't about to give up its crown to GIMP; Lightroom isn't losing to Darktable; and FreeCAD isn't even in the rear view mirror of Solidworks.

I wonder what will be the next category of open source to pull ahead? Godot is rapidly gaining users/mindshare while Unity seems to be collapsing, but Unreal is still the king of game engines for now. Krita is a viable alternative for digital painting.

What Blender achieved is that lots of university programmes have started teaching Blender or becoming 'tool agnostic'. Studios have also started diversifying their pipelines (this coincidences with studios adopting Unreal and increasing usage of Houdini).

So while Maya is currently the standard, I don't believe that it's growing. It'll probably be around still in 20 years, with lots of studios having built their pipelines and tooling around it, with lots of people being trained in it, and because it's at the moment still better than Blender in some aspects like rigging and animation (afaik).

IMHO that's only still true because large studios can't afford to move their entire highly customized production pipeline which they had built around Maya for nearly three decades to any other tool (Blender or not), even if they desparately want a divorce from Autodesk. Autodesk basically has them locked in and can milk them until all eternity or the studios go bankrupt.

I bet that the next generation of CGI and game studios will be built around Blender (and not based on the quality of those tools, but because of Autodesk business practices).

(edit: somehow my brain switched Adobe and Autodesk - forgiveable though because both use the same 'milking existing customers' strategy heh)

Super small nit (or info tidbit), but it doesn't take away from your overall message regarding production and scene scale.

Pixar does not and has not used Maya as the primary studio application, it's really only used for asset modeling and some minor shading tasks like UV generation and some Ptex painting. The actual studio app is Presto, which is an in-house tool Pixar has developed over the years since its earliest productions. All other DCCs are team/task specific.

Dreamworks is similar with their tool, Presto, IIRC. Walt Disney Animation Studio (WDAS) does use Maya as the core app last I saw, but I don't know if they've made any headway with evaluating Presto since 2019...

Mine aren't: GIMP is okay, FreeCAD is a complete joke. It is painfully obvious that their development is done primarily by F/LOSS enthusiasts rather than by industry professionals and UX designers. They are closer to being a random collection of features than a professional workhorse. You might eventually get the job done, but compared to the proprietary competition it is woefully incomplete, overly complicated, and significantly buggier.

The poor quality of FreeCAD is the main reason my 3D printer is collecting dust. As a Linux-only user the proprietary alternatives mostly aren't available to me, and FreeCAD is bad enough that I'd rather not do CAD at all. The Ondsel fork was looking promising for a while, but sadly that died off.

KiCad, for PCB design. They have been making massive improvements over the last few years, and with proprietary solutions shutting down (Eagle) or being unaffordable (Altium) Kicad is now by far the best option for both hobbyists and small companies.

With the release of KiCad 5 in 2018 it went from being "a pain to use to, but technically sufficient" to being a genuine option for less-demanding professionals. Since then they've been absolutely killing it, with major releases happening once a year and bringing enough quality-of-life improvements that it is actually hard to keep track of all of them.

From the type of new features it is very obvious that a lot of professional users are now showing interest in the application, and as we've seen with Blender a trickle of professional adoption can quickly turn into a flood which takes over the entire market.

KiCad still has a long way to go when it comes to complex high-speed boards (nobody in their right mind would use it to design an EPYC motherboard, for example), but it is absolutely going to steamroll the competition when it comes to the cookie-cutter 2/4/6 layer PCBs in all the everyday consumer products.

KiCAD becomes better and better, but one limitation embedded into its DNA is very annoying: one project - one schematic - one PCB.

It is very kludgy and cumbersome to split project into several PCB (for example, stack of PCBs connected by backplane or headers, like Arduino & Shield for it) and/or to have variations of the PCBs for one schematics, like TH and SMD variants of the PCB for exactly same schematics.

Even in my very modest almost-electrical (as opposed to electronic) projects I need one or another from time to time.

As far as I understand it is limitation which is not easy to fix, because all architecture of KiCAD is based on this 1-1-1 principle.

the epiphany moment was when the dev team stopped listening to the neckbeards that wanted things different for the sake of them being different, and started listening to professionals that wanted more sane workflows. There must be a reason if all industry does things simillar ways, other than inertia.

Guess what, user adoption increased dramatically, because it became pleasant (or tolerable) to use by people that used literally any other program.

V8 included in the core many things that were plugins before, and replaced the old utilities that the neckbeards in the forum were crying to keep, or else! (or else more adoption.)

V9 had even more many improvements, but also many regressions, over V8. V10 might be the release that truly consolidates the core of the suite and then they can start really focus on high speed designs.

I've navigated many programs over my career, and unless a future employer mandates me to use Altium, or purely technical reasons (8+ layer, high speed designs) requires me to use Cadence, only kicad for me.

Incidentally, it feels like this past two years freeCAD GIMP and Inkscape have started moving away from listening to noisy members of the community, to useful members of the community. I'm seeing a slow but steady progress that will eventually accelerate and make both toold true alternatives, as it happened with KiCAD (though it will really be tough for GIMP, even if it's perfectly usable for many, many tasks, any graphic designer will kick and scream if they're not given the adobe suite, pity.)

Myself, i do very little basic graphics like replicate buttons and such things to not bother my colleague, or apply correction to my photos, i proudly do that in GIMP and inkscape.

I would never recommend freecad to anybody, even though this this the only CAD I use, and I actually write python for it for some automation.

I cannot live without freecad. But damn it's a mess.

As a game developer, I'm really rooting for open source game engines.

Unity and Unreal are dinosaurs that target the shrinking console market. Godot is being built in their image. My hope is that something more versatile like Bevy becomes common so that we have something that could potentially compete with the next generation of Roblox.

Do you think the next generation of Roblox will be a dominating games engine?

Possibly Audacity, given the direction v4 is taking. Great video essay / update here: https://youtu.be/QYM3TWf_G38

>>It has rendered Maya nearly obsolete

Hadn’t heard that. How many AAA vfx studios have left Maya for Blender?

I’m rooting for gimp but they are truly a decade behind photoshop. I don’t know how they can compete. Luckily it does not seem like they are in the market for professionals so the need to match Photoshop isn’t quite as high

really? I haven't done 3D rendering in a long time, admittedly, but back then Maya and Lightwave were miles ahead of Blender. Rhino3D too. Even 3DSMax was better. Lightwave seems to have sadly fallen off (unfortunately, IMO it was the best at one point, had excellent ray tracing). I didn't really Blender had come such a long way -- that's great.

Since you mention niches: Adobe InDesign has no OSS competition at all, and Illustrator is still much better than Inkscape.

Every time Blender has a new update, I scroll and I'm amazed by how much is in it. Then I realize my scrollbar is only halfway through.

Radial tiling my beloved, and a seemingly far more straightforward array modifier <3 Faster volume scattering for non-homogenous volumes.

For those wondering "where the AI is", the new Convolve Node might be it :) Convolutions are a pretty generic signal processing operation (Hadamard product) which are also used in neural networks which work with images. Realistically though, this will be mostly useful for wonky hand-crafted blurs.

The new sequencer looks fantastic, too. I always went to DaVinci Resolve but I might be able to go full blender. Compositor modifiers in the sequencer is also very welcome.

This is incredible for me.
