So I imported a model of my sim into blender to mess around with renders and maybe try and make some CC, but (as usually the case with game extracted models) the model has these 'artifacts':

enter image description here

How do I get rid of them? I removed doubles, reset vectors and recalculated normals, cleared sharps, have 2 light sources with a plane underneath to bounce light off of, idk what else to do... Edit: Subdivision surface doesn't fix it, and on the other model I imported smooth shading doesn't work at all

Sims likes to use overlapping geometry for things like beards and hair and upon removing doubles the polygons still look messed up. I remember there might be double polygons sometimes but I don't remember how to clean them. This one shows only with subsurf enter image description here

And random walk subsurf for some reason looks like this (after removing doubles)enter image description here

Ok, I see why the second model is messed up now enter image description here

The first one looks alright though, must be something else...

The proposed answer was wrong, I mentioned I checked the normals and then someone proposes to check the normals and closes the question.

  • $\begingroup$ Looks like a seam. Is the Color Space value of the normal image texture set to Non-Color? $\endgroup$

I had somewhat of the same issue and my model looked like this: enter image description here

I fixed it by:

  1. going into edit mode
  2. selecting all faces
  3. pressing ALT+N and selecting "Recalculate Outside": Select Recalculate Outside

After that, my problem was fixed: enter image description here

I hope I could help anyone, even though this question is 1.5 years old.
