Meshes are constantly corrupted in topologies where I use Boolean

Whenever I use boolean the mesh gets distorted and sharp lines start to appear on it. I tried to fix it but I don’t really have an idea how to do it.

That is not corruption, but smoothing artifacts due to the presence of skinny triangles (which had to be created due to the topology in the area).

To fix, you can…

  • Model the fuel cap manually using proper topology
  • Use bracing edges and topology changes to assist the boolean operation (with Geometry Nodes, this can be followed up by a merge doubles operation).
  • Use more advanced normal data transfer from a clean mesh

If Blender has a robust NURBS toolset then it would be recommended to use that instead, because that is how professionals model vehicles usually, but we do not.

This is not a damage, it is a characteristic of the mesh. :thinking:
An invisible edge exists, which connects Vertex.

Try using WeightedNormal modifiers to see if they can be improved.
