I converted a model to *.obj and imported in blender, but the surface normals are all weird.
- Recalculating or flipping normals does not work.
- Looking at the “vertex-per-face” normals I see that the normals seem aligned parallel with the surface!
- One thing I’ve had succes with is sculpting the object with retopology on and zero strength. This fixes the normals, but the topology is messed up.
- Setting vertex normals from faces makes the mesh look like smooth shading is turned on. Toggling between smooth and sharp returns (more or less) to the initial problem.
Attaching an example in case anyone want to have a look themselves.
