Notes :
- Loop Subdivision. Catmull-Clark for both quads and triangles is supported
- Points. Have been partially implemented. Point falloff is not yet supported
- The built-in curvature doesn't match RIS and will be receiving enhancements in a future releaseis not yet supported
- Object attributes such as maxdiffusedepth and maxspeculardepth not yet implemented
