I'm stuck in a problem for last few days with my project. My AO bake isn't very smooth. When I increase the size of the UV island, the error gets smaller, but it does not go away. I tried increasing the island margin and bake margin, but neither works.

3D View UV Image Editor

My uv map is 2048px and my project does not contain many faces.

Here are my settings:

  • AO Factor: 0.10 ADD
  • Environment Light: 1.0 (White)
  • Gather Raytrace,
  • Attenuation: 10.000,
  • Falloff: 1.000,
  • Constant QMC: 12 Samples (I have changed this value many times but got the same result)

    $\begingroup$ Welcome to Blender.SE! You are saying the texture is 2048, but how much surface does the interested part cover? Can you show the whole UV space? $\endgroup$

  • $\begingroup$ When a increase the size of the face in UV Space the problem gets smaller. image.prntscr.com/image/R9LzvqTKTSi_inN0r2zb8Q.png $\endgroup$

  • $\begingroup$ So it looks like it's only a resolution issue. $\endgroup$

  • $\begingroup$ Yeah, i think it is but i can't increase the size of my resolution and my project is not much high polly, to have big resolution size. I think i need to find another way to discrease this problems. And i will try a 4048px resolution. $\endgroup$

    $\begingroup$ You can also try to optimze your UV layout in order to give to the more meaningful faces the resolution they need. Without other information about your specific project, I can't tell you more than this. $\endgroup$

One solution is to Boolean your intersecting pieces together:


  • $\begingroup$ It didn't work, a put the modifier Boolean diferrence but the same result. $\endgroup$

  • $\begingroup$ @Augusto - Did you apply the modifier? If not the geometry (and presumably the UVs) will be the same as before. I have not checked to see, but I would not expect this to work until you actually apply and make permanent the boolean modifier. $\endgroup$
