Maya Transfer Maps Ambient Occlusion Hack
For some unknown reason Autodesk decided that when using the Transfer Maps tool to create an ambient occlusion texture, the ‘Spread’ attribute was unnecessary (even though it’s the main control for altering the intensity of the occlusion!).
So I’ve hacked it in, now when creating an ambient occlusion texture you get the attributes: Rays, Max Depth, and Spread.
I’ve made scripts for each version of Maya, make sure you use the right one.
