Ambient Occlusion banding issues

lloyd

Hello!

When doing a AO bake in Max using a skylight and light tracer I sometimes get banding issues, as if parts of the HP are sticking though and causing problems,

However it doesn't happen everywhere. in this place the HP is sticking out but is also is in other unaffected areas.



does anyone know what causes this or what i might be doing wrong?

As I watch the picture I might say you have model parts that cross each other and have intersections. You need to explode your model before you bake the maps, else you will get such results. But you've already said that, or? (It wasn't quite clear for me sry ^^)

Maybe it's Max related, have you tested another tool, like xNormal for baking? Get same results?

Yeah its not extra bits cutting in, it only seems to happen on some bits

This could be the lowpoly affecting the AO casting... try setting the lowpoly to not cast shadows.
