Ok i have another question:

Now I'm having difficulty converting my polygons BACK to sub divisions. My script editor reads:

Error: polyToSubdiv1 (Poly To Subdiv Node): One or more vertices is nonmanifold.
// Nonmanifold geometry cannot be converted to a subdivision surface.
// To clean up nonmanifold vertices, use Mesh->Cleanup with the nonmanifold option. /

So i went to Mesh and hit Cleanup, but im not sure what it accomplished. I tried converting again but it still didnt work. In the tutorial, Kurt says i might have to raise the number of maximum base mesh faces, but after trying severl numbers, i was still unsuccessful.

Any suggestions would be strongly appreciated. I will keep experimenting. Thanks!
