VRay Subdivision

This script will go through all your selected meshes in your scene and add or delete a subdivision tag. There is a window to set all your normal subdivision settings and check boxes.  There is also a tab that will add or delete rounded edges to your selected objects and you can set the round edge radius.

To Run: Select the objects you want to add subdivision or rounded edges to then run the script.

#VRay Subdivision and Rounded Edges for Maya version 2.0.0
#Bryanna London www.bryannalondon.com
#!/usr/bin/env python
#UPDATED for VRay 2.4 and later

#Adds Vray Subdivision tag to all selected geo. You can also
#Add the vray rounded edges tag to all selected geo.
