Hi @sonygod,

Are both UVs imported and used in Unity ?
Would if be possible to share the sketchfab URL so that I can check what has been exported and why you don't have the switch option ?

Thanks,

Hi,

Sketchfab is handling UVs a such way that the index is often not relevant (i.e the order in the geometry is often different from the order in the dropdown on Sketchfab) , we are aware of this and it could be improved.
Most of the time, everything should be set correctly so that you don't need to go in the 3D editor to fix settings like that.
I downloaded your sample and will take a look, because this should be a seamless workflow.

Thanks for the samples and details!
