Is it possible to get the UV maps from the ergs? They're needed to have the textures assigned properly. Saving geometry without UVs makes these geometry almost useless for tests.
If not, then it would be a great idea to have this as a new feature in the next update.
Currently, we can't export the UV maps associated with the geometry in the DX 9-11 version of the tool. But I believe it's possible in the DX12 version of the tool.
Which graphics API is your application using?
