I opened a birds fbx file from fab (the new unreal engine marketplace), and it played the animation and I could see the textures.
I tried to open an animated fbx from Mixamo (Mixamo is owned by Adobe) and it didn’t display the animation but it did display the mesh. That’s funny that birds work, but not Adobe’s own fbx files. The animation plays fine in Unreal Engine. I have some other issues with Mixamo as well. I have to post some questions to their forum.
Next I tried to open the ~30 mb infinigen indoor usd scene. It took about a minute to open, but it looks great.
This was done on my Windows machine. If I need it, I’ll install it for Mac too.
