eh. sorry to bother you again but i need some ilumination again 
i had a look on the panda docu and found out that panda can read and write vertex colors, but can i actually use them?
i’d like to use them to store lightning information (baked into with blender).
can panda handle this?
Lightning ? Did you mean lighting ?
Of course Panda can handle this, try to check the collision detection tutorial shipped with Panda. Take a deep look, you’ll realize that the maze interior (intersection of wall-floor) vertices hold the black color (0,0,0), and the rest are (1,1,1).
omg… how could i miss it!?
thx for telling me
… ah… course lighting… 
looks more like a pipeline problem now. looks like the x exporter doesnt really write vertexcolors. 
but i’m really glad to know that panda does the job =)
edit: jep. Fabius egg exporter does the job.
