troube baking AO to texture

[benjerman]

Hello. i am trying to bake my AO pass unto the texture via polygons colours>batch bake (mental ray)>options, in Maya 8. the colour mode is Light and Colour. When i go to convert i get the following error:

cmd : convertLightmapSetup -camera persp -sh -bakeSetOverride tmpTextureBakeSet5 -bakeAll -showcpv
// Error: [MentalRay Baking Setup]: grpNodeIter.next(), File: C:\engserv\rbuild\153\client\Maya\src\MentalRay\pl ugin\ConvertLightmapSetup.C, Line: 363 //
// Error: [MentalRay Baking Setup]: searchAssociatedGroups( dagPath, MFn::kShadingEngine, sets), File: C:\engserv\rbuild\153\client\Maya\src\MentalRay\pl ugin\ConvertLightmapSetup.C, Line: 1319 //
// Error: [MentalRay Baking Setup]: processShape( dagPath, MObject::kNullObj), File: C:\engserv\rbuild\153\client\Maya\src\MentalRay\pl ugin\ConvertLightmapSetup.C, Line: 860 //

I don't follow what this means. Anyone translate/tell me what im doing wrong?

why dont u use occlusion mode instead of color and light mode for occ baking. I use it everyday for occ baking
