Mudbox AO problem

snow

Hi all,

Just made a tilable texture in Mudbox 2009. Turns out my Mudbox 2009 version couldn't bake AO's (no option under Maps anywhere). I've saved the file, and opened it into Mudbox 2010. I now can bake AO's, however the result is a section (roughly 1/4) of the AO bake is missing, and shows up as blue in the Mudbox viewport. To make things more confusing, baking normal map and displacement maps works perfectly. Can anybody please offer any advice?

Left : Mudbox Viewport Right: Final AO texture



Thanks in advance.

your uvs are to close to the border...
mudbox is reading your uvs in uv tiles...

ao in mudbox will be baked with the gpu so they are different to dispmaps...

Thanks.

Is this fixable without having to redo it all again?

check the uvs in max or maya and repair it...
and then go to file --> import uv

Thanks oglu.

I redid the uv's, imported using Vertex ID, which i assume is the correct method.

I am now getting this really weird puzzle effect.

Any suggestions?

looks like moved uv shells...
take a second look...

So I've saved off a displacement map from my original file, created a new scene with the newly uv'd plane and sculpted the model using the displacement map.

AO's are now working.

Thanks.
