For a long time, there was a DVD on the Autodesk Online Store entitled "Maya Techniques | Writing Creature Deformers". However, Autodesk recently removed it from their store, and no longer makes it available through any channels. It appears on several other online vendors' sites, but all of those are special order - coming straight from Autodesk, which means they'll never get any more in.
This is the only resource I have been able to find on the subject of custom deformer creation in Maya, but am now unable to find a copy for purchase. Is there a chance that anybody knows of somewhere I can access the material on this disc? ...whether by legitimate or "questionable" means?
