I'm trying to model Mahjong tiles for practice and I came across the challenge of filling the face around the details. In order to streamline the process I created a module of the detail, which I can then copy around and fill the rest of the face with quads easier. Screenshot of "Module" The coloured sections sink into the face so I couldn't just put the details on top of a big face. Example of the tile with faces filed in I'm using subD modifier to create the smooth circles and bevel modifier to (mostly) contain the different materials. However there is still overlap between the colour material and the white in the bottom right of the circle. This effect was worse before I added the bevel. Object mode view

Close up of the issue both object mode and edit mode. There is a single bevel weight around the outer most circle. Object Mode Result Edit Mode

Things I've checked:

  • All normals are facing the right way.
  • There are not overlapping vertices.
  • Model scale is cleared.
  • I've tried adjusting the bevel strength/number of segments.

Having said normals are correct, with face orientation view on and Object mode, there are red artifacts that I can't work out. The model looks fine in those locations when not in face orientation mode. It's just the material leaking Face Orientation mode & Object Mode

If anyone could offer some advice, I'd highly appreciate it. I've found issues with subD modifier and materials overlapping in my practices. For example, if I create a two-tone bowl the two tones would overlap unless I create a few loops around where I want it to actually separate. If there is a name of this phenomenom, please let me know!

Thank you for your time.

  • $\begingroup$ i would recommend providing your blend file so we can check it out and don't have to ask in comments. e.g. we have no idea how you material looks like, what kind of uv mapping you have etc. $\endgroup$

  • $\begingroup$ That makes sense! Sorry I’m new here and didn’t think that was an option. I’m out for the day but will add the blend file later, you’ve given me an idea to check the UV mapping too. I never considered that when just working with simple materials. $\endgroup$

    $\begingroup$ @RobinBetts Thank you for linking that! I'm using these tiles as a mesh modeling exercise but I'm definitely gonna refer to this later when I look more into textures! Appreciate it. $\endgroup$

I resolved this by removing the bevel and adding seams on the outer edge of the outermost circle. Even without any UV unwrapping, this helped me separate the different materials properly.
