Corrupt USD Export

[chrisperrella_nvda]

Hi! It appears that there are a number of errors in materials when exporting a USD file.

[hydra] the output name for UVTexture Node is invalid.(Valid choices are r/g/b/a/rgb)
[hydra] unexpected type hold by material param _normal

Material::UpdatePreviewSurfaceParams(class pxrInternal_v0_20__pxrReserved__::HdSceneDelegate *,struct pxrInternal_v0_20__pxrReserved__::HdMaterialNetwork &,struct pxrInternal_v0_20__pxrReserved__::HdMaterialNode *,bool,bool &,bool &)(): Assertion (false) failed.

Its difficult to debug as opening the material crashes the engine. Is there anything I can do to help provide repro steps to assist in resolving this issue?

Hello,

Thank you for the report

When you say "crashes the engine", which engine do you mean?

When you export, are you exporting the USD from using export static mesh or export to game? (both can export USD, but the results can be quite different)

Hey Greg, I'm using the export to game, export to mesh isn't available in my version of Speedtree. Engine is Omniverse.
