I'm modelling a coat for a character, and I have those weird dark grey artefacts on some faces.
A few things :
As you can see, there's no overlapping faces, no triangles either, it has no modifier on it except for the mirror modifier.
I've already tried to :
- Shade it smooth or flat,
- Flip and Recalculate the Normals
- Apply all transforms in Object Mode, and
- Clean Up for Loose Edges/Vertices/Faces, and Merge By distance.
- I've also deleted and rebuilt those faces but those artefacts remains.
Any idea ?
