Mesh parts bleed between each other


Issue

Mesh geometry bleeds on other parts and create artifacts.


Explanation

The baking process sends rays from the low-poly mesh surface to hit the high-poly mesh to create a match. Sometimes the rays go too far and hit the wrong geometry, creating the bleeding and artifacts.

Solution

A few solutions are available to avoid this issue :

  • Use the Matching by Name feature to isolate the meshes
  • Use a cage to limit the ray distance.
  • Change the default ray distance in the common baker settings to a lower value.
