AO artifacts when using MR

LEViATHAN

I'm getting some strange artifacts when baking AOs using MR in Max 2009. They look like... stains? It's not only happening with this particular model, same deal when trying to bake other objects.

This is a pretty recent thing, never really happened until a couple of weeks ago. Ideas?

/e It's not xforms, it renders the same pattern consistently.

How are you baking the AO? using an AO node or using the AO setting in RTT?
what is your unit scale? how big is the object in relation to it.

can you render the object in a normal render using AO, does it work?

do you have overlapping uvs?

what camera is this?

Does it bake fine with scanline?

This is a common problem with MR rendering AO maps I get, the solution used is to put a push modifier on your lowpoly and shrink it so that the lowpoly is just barely inside the highpoly. This is only for your AO, not normal maps, etc.

In your render to texture dialog... in the "selected Element Unique Settings" set your setting to
Spread : 1.0
Max dist: how ever long your object is
Falloff: 0.0

then post another pic
