how about adding a internal octree-like structure for collidable meshes if a certain number of vertices is reached? subdivide them in groups and subdivide them again if a sub-group is still above the limit. (just as idea for some future panda versions).
could help with the collission detection of detailed meshes.
might be intresting for culling/clipping of large objects like environments etc. so you wouldnt have to splitt it ourself while creating the stuff.
my idea would’ve been something like
model = loader.loadOctreeModel(“path/to/model”,optional vertex count for splitting groups)
