Hi Ondrej, here are the steps to reproduce:
- export a textured mesh (the reason it’s textured before retopology is because it’s useful to see how the texture is projected on the raw mesh and what areas need to be retologized.
- in blender, import the model, create and add new faces to the model without unwrapping (like the cylinder that I’ve added to the scan here)
- export the model and re-import into Blender.
- the new faces that were added in blender were deleted during import and indicated in the log.
So, upon further inspection, any faces that don’t occupy the “correct” amount of space in the UV’s get discarded during import.
This is an issue because the typical workflow (amongst quite a few people that I know who use RC) is essentially some version of what I just described.
Suggestion: all RC needs to do is import in a mesh for us to unwrap and texture in-app. Currently the importer is wayyy to restrictive with what sort of faces and UV’s it accepts during import.
All I wanna do is retopo outside of RC and re-import it for texturing, not need to keep a track of all the faces that I adjust/create and unwrap them just so I can re-import into RC for unwraping+texturing.
Hope that’s clear! Let me know if I can provide any more info.
