AO Light leaks where meshes intersect in substance painter.

Spiralface · Jul 2016

Trying to bake good AO maps in substance Painter.

Getting white "halo" effects in my AO bakes where two seperate meshes intersect with one another.

Trying to find a way to correct this in the AO maps. Any help appreciated.

I get this every time I bake AO as well, so I'm curious to a good way of doing it also. I tend to just bake it in Max now.

Make sure you uncheck the Ignore Backface option in the AO bake settings.

That did the trick. Thanks.

Follow up question. The white line seems to have been replaced with essentially a black "outline." where there are intersecting geo mesh components. A similar intersection on a more flat plane doesn't seem to have these kinds of harsh outlines despite similar setups. (Only difference is one is on a curved surface, the other a flat plane.)

Is there any way to either soften the transition from the pure black to the gradients? Or if there is something I need to do to get similar results to what I get on the bottom?

Sometimes ill throw a blurr filter on my low to low AO, then duplicate and blurr some more. Its subtle enough that the inaccuracies are hardly if not noticeable. I do not recommend for hero assets

Changing the distribution setting from "Cosine" to "Uniform" might help avoid white lines in corner like those.
