I'm exporting a little particle waterfall splash from 3ds max as a sequence of OBJs. Each OBJ has several triangles with different values for visibility. I have two problems: the first, naturally, is to export these values per-polygon (a simple MaxScript should produce a companion text file describing their visibilty), and the second, of course, is to apply these visibilities per-polygon in jpct (lest I have to have an Object3D per polygon, which seems bizarre memory-wasteful). Is this possible?
