Right now, if in order to use Panda for your world, you just use all 3D models in Panda format (egg or bam or whatnot). This means that everyone connecting to the world must be using Panda and not Ogre. The eventual plan is to make it it so that you can export models in both formats and have MV3D use the proper one for the renderer you selected, but that isn’t in yet.
Thanks,
