Can someone help me identify or solve the problem for my 3D model in Substance Painter? When I import my model as an FBX from Blender, I learned that before starting to do anything you should bake the mesh. So, I baked the mesh, unchecked the normal and ID. But then (I suppose it's Substance) adds some weird triangles on the mesh. I tried to check if the problem lies within my Blender model, but I can't find any issues there, checked for double faces of vertices, I applied the scale and rotation and that doesn't seem to be the solution. Maybe someone here knows the solution? Thanks in advance!
Do you have any overlapping UV islands? You can check that when unwrapping in Blender.
Thank you, that was indeed the problem. I did not realise that all the loose objects that share one material need to be in the same UV map. Problem solved, thanks for your help!
You're welcome, I'm glad you got it sorted.
Having the same problem with a model created in Rhino 7, can you post a tutorial for this? how dis you solve the problem in Blender? Thanks
