Tutorial: Ambient Occlusion in Maya - by Alchemist101

Individually. They should still pick up AO from other visible geometry regardless of the UV, so you wont be losing any details. In fact, you'd be better off splitting the mesh into different pieces for the AO and hiding some anyway due to the moving parts involved - it would look funny if AO from the turret gets baked onto the front of the tank, as it will be there even if the turret is rotated 180 degrees.

Hi Cryrid, thanks a lot......I finally got a good AO map baked at last. I discovered the mistake that I did very often. After assigning the materials to the different objects, I use to combine them before baking the AO and that's where the problem use to occur. Any ways thanks for the tip.
