hello, so im having a problem with my Uvs, its seems that they are messed up, you can see it in the GIF provided, i think this is causing other problems such as Why my surface noise is not automatically been applied (not sure though)
** the Surface noise related problem ( Surface noise Question ) **
Hi @akram_fex
A couple of things that you can try…
Check the mesh of that subtool using “Tool > Geometry > MeshIntegrity > Check Mesh Integrity”
Create your UV’s using UV Master plugin instead of the Uvc option you are using.
thank you for your replay, i fixed the issue, it was the Dynamic subdivision On in the background, deactivating it fixed it, you introduced to me MeshIntegrity so for that im grateful
