Hi Ondrej,
According to our knowledge, this is happening just for FBX file. Can you confirm that?
I’m using OBJ’s here. NOTE: this only happens one meshes that are unwrapped/textured, so likely tied directly to the UVs of the new faces that are introduced during retopology.
There should be also a workaround to resave the model in some 3rd party application and then import it to RealityCapture
Resave? The only real workaround is the unwrap all the new faces and make sure they’re contained within the bounds of the texture (even if they’re overlapping with other face UV’s). I believe this wasn’t the case in the past.
