Blender Proposal: Collaborate with other projects to create a new 3D interchange format (blender.community)

It is hard to get models out of Blender (correctly and without loosing half the work).

Gamedev relevant open-source projects should come together to create a new 3D interchange format. More in the Right-Click Select post.

I've submitted this proposal to other open source projects as well:

USD has been a true life saver for me for a long time because it really just works. Funnily enough Pixar invented it because they needed a universal format for their workflow but nothing of the sort existed. And of course the beauty of open source is that everyone can contribute which makes it far superior to most formats by default. Godot has been really sleeping on this as have many others.

I mention why USD does not work in the proposal:

USD is not 'just a 3d format'. Its scope is far bigger and more comparable to an entire game-engine project rather than a single asset. It can make use of FBX files, and it could make use of this proposed format in the same way. USD does not replace FBX, or any other file format like that, and it's very complex. Godot doesn't support USD.

Last month, I tried to get a model from Blender 4.2 to Unity 2022 in USD. It omitted the main armature. I quadruple checked all settings^^ USD may be very nice for VFX, gamedev is fundamentally different. I need 'just a fileformat'. If USD just worked across the board, I would have likely just used that. It is very complex and appropriately hard to implement. In don't fault Godot at all for not supporting it.
