I literally just had Claude build a 3D modeler slice of Blender that I wanted but that also works in VR [video: (https://www.reddit.com/r/aigamedev/s/q5Y6cskYb9)]

I think the value of adapting full tools to your own workflow far outweighs the maintenance costs nowadays. The tool above for instance took my agent a couple hours and it was good to go. It wasn’t a small slice by any means either: it supports edit/obj mode, extrude, loop cuts, modifiers like subdiv, save/load, undo/redo, bones, auto rig, posing, and more.

Mind you, this is a slice of an open source tool which was still outside of what I wanted from it. Cost wasn’t even part of the equation here.

That's a pretty neat looking program.

Since Blender is OSS, you could probably use one of the existing VR views for Blender and write a bunch of in-app Python scripts to do what you want, if you wanted to also be able to output to Blender files and work within Blender already.

This looks like a pretty well-trodden area in Blender.

But see, i dont want that. I want a modeler that works how i want, some things that work like Blender and others that work a different way.

Adding scripts into an existing product does not serve this.

I think we are entering into a new era where we don’t need to accept fully featured software with all of its decisions should they not fit our wants

You might be surprised just how much you can rewrite of Blender's UI if you want to.

And you get battle-tested software and a huge collection of existing plugins, operational modes, export formats, all that. Fully bespoke software for everything you want is a way toward losing interoperability between people and platforms.

It doesnt have to be one or the other: you can have custom software that still works within existing/interoperable formats, as I’m doing here (im not planning to reinvent OBJ/FBX/BLEND)

But building up as opposed to building down is freeing in that I can also pull in ideas from Houdini and mix them in. Not to mention BECAUSE Blender is OSS, i can also use it as reference for implementations of particular things should I need that too.

IMO, this kind of full customization is going to become far more commonplace.

Very cool. I’m in the process of creating a video game and building all the tooling around it, both for me and the players. And also, for doing things like recording a quick sequence of gameplay, “sandwiching” it with an intro/otro and posting to YouTube, then ingesting the engagement data to show on the internal player… still early days, not enough data to start optimizing on it, but I’m really enjoying building exactly what I want as I go along

You mention that you have no plans to share. Any chance I could persuade you otherwise? I maintain Open Brush and Open Blocks and I'm very interested in getting something more complex working for 3d modelling and actually shipping it to the various app stores. I've got a few different approaches in mind but using Blender as a base it quite appealing.

I could start from scratch obviously - but seems a shame.

Re:KetchUp – Open-source SketchUp alternative built with Rus... by dyarosla on Monday November 09, 2026 @08:45AM (#50425526)
This really isn’t Blender as a base- more like uses Blender as a base reference.

I think both those apps are great and happy to know folks like you are maintaining them; this one though is simply more of a personal software than a path to an OSS project!
