I’m using blender to create my models and then attempting to see them in unreal engine.
Is omniverse supposed to work? i’m trying to test it so i can explain what it does to others but i’m not able to give them anything positive currently.
Unreal crashes upon attempting to open the USD files. Even if the scene is just two small meshes. The meshes are exported from the omniverse version of blender.
I’ve tried both 5.2 & 5.3 omniverse connector- same crash.
here is one of my crash dumps.
