Ambient Occlusion with unknown banding


I am trying to do some AO rendering and baking but the result looks not correct to me. I have tried both Blender Internal and Cycles for baking with Blender 2.71.

Does anyone have an idea?

Testrendering: with banding problem

Same rendering:

01.blend (835 KB)

Under Postprocessing in the Render tab you will find a setting called “Dither” (both for Cycles and Blender Internal), which is exactly for breaking up banding in renders:

P.S.: Are you sure you need 10000 (100 x 100) Cycles samples on that?!?

Thanks for the help, I tried this in BI and in Cycles, both testrenderings looks good, but the baked AO texture has still the same banding problem.
