As the title suggests, clicking the "Export to SceneKit" button indeed converts a USD to .scn but removes the normals in the process if the mesh has blendshapes. When I export the same file without any blendshapes / morphtargets, the normals stay on as expected. If I try to create normals in the scenekit editor (adding them as a new geometry source) Xcode crashes (no matter if there are blendshapes or not)
I've tried loading the resulting scene with
[SCNSceneSource.LoadingOption.createNormalsIfAbsent : true]
but this doesn't change anything either.
I suppose this is a bug?
My last resort is to load my character without any blendshapes and then add the targets from a different scene.
Thanks for any insight!
