as someone who works in that area, USD will be pretty awesome once it is well integrated in the respective 3D applications. Through MaterialX it'll even be possible to export complex shaders through different applications. It'll be much easier to use different programs on a single project.
Nvidia already pushes USD with their Omniverse thing. Whoever doesn't join the new standards shoots themself in the foot.
I believe Autodesk is seriously threatened by Blender (Adobe, Nvidia and Apple have invested in Blender already), and if they don't implement the standards that studios demand they'll just remain on the losing side.
To be fair, Maya’s support for USD blows Blender’s out of the water. It’s natural that Autodesk is in this, they’ve been supporting USD greatly for years. It is Blender that is a bit behind on USD/Hydra/Material X (but there is hope for the future).
yeah, sadly. There is a lot of interest, and I guess the Blender Devs have a hard time managing it all of the contributions. they are actually hiring someone who can help out with all of that stuff
