AO leaves a slight halo around a lot of things

Serp

I've always had this in my models. I believe I made the ao for this in Max.

One good question is: Are you baking the AO from your high poly or from your normal mapped asset. Right now the shading looks to be following the normal mapping, and at those points the normals point out of the groove, and so will be less occluded than their neighbors pointing toward the obstruction.

If those areas are along UV seams, you might need to add some more padding to the bake.

AO doesnt pick up back facing geometry. you can see the parts that suffer from the problem are where there is overlapping geometry. If you look at your map you will see that areas which are covered by overlaps are white. since the map is low res the white bleeds out. adding bleed wont fix this.

I usually paint over these when i see them. If your using light tracer i think you can set the material to 2 sided in the material editor and it fixes the problem.


perhaps this pic will clarify

Yeah, this is certainly the issue.
