Maybe because vertex points or point clouds meshes are not so easy to handle. I do not know whether free 3D modelers like Anim8tor or Blender can manage the point clouds. The most easy way to get points with 3D modelers which doesn't handle them, is to export a mesh as .OBJ file without normals and textures and then do remove faces within a text editor; that is, by deleting all the faces' strings and to hold just the vertex. Its main problem is that points' distribution does resemble the meshes' shape; there isn't enough "randomization" into such a method. The basic meshes must be "randomized" for themselves, before to do that. Preliminary "chaotic" sculpting of the meshes can help. I use Perl scripts to handle points from OBJ, and for OBJ to CMOD conversion as well.
