"""
Here we settle up a simple scene with a wide terrain surface, where to compare 2 different floor colliders applied on it: the first is a whole single collision mesh with approx. 16.000 polygons and the other is the same former mesh but after being octreefied, using the octree script incorporated in the blender chicken exporter - have to know that the resulting model is not composed by a whole mesh anymore but rather by dozens of small mesh chunks that will relief the panda collision system for an extent you'll going to see by yourself with this snippet. The real deal with this tutorial is not much how to settle the collisions, explained in detail in former steps, but rather how to export your collision meshes with blender and how will change here the usual floor collision settings, because of the octreefication. I suggest you to check infos in oc3models.blend first and then return down here to continue.
