Thanks to everybody for answers!
The mesh camera brought me to lightmap baking, which seems to be what I need:
All surfaces are unwrapped to a UV-map, that map then stores the illumination
I use Poseray to convert my .ogj to POVRay-scenes, then the POVRay lightmapping
helper by Jaime Vives Piqueres.
The problem now: the lightmaps that are generated are mostly black, only some
patches contain some very minute amounts of light.
The scene I use to test everything is a plain white cube with a spotlight on it.
(axes are non-baked).
The resulting lightmap is mostly dark, just some light along the seams.
Any idea what im doing wrong here?
