Lightmaps across multiple node paths

Hey all,

I’ve read up on some of the lightmapping threads for Panda3D here in the forums, and if I understand correctly it works best if your environment is one large mesh. So if I wanted to create a level using many instances of modular pieces, I have to reference them during the modelling stage and export the entire thing to egg.

I’ve found the egg exporter I’m using (Maya 2008) to be quite slow on large files, and I don’t see the point of duplicating geometry needlessly. Is there any way to have multiple instances of a model in a scene with a second set of UVs but only one instance of the model on disk?
