ok - a quick question about zbrush and displacement maps. when i export a displacement map from zbrush - i use the displacement tab under my tool menu. i turn on adaptive, put dpres at 2048, intensity between 3-6, press mode and hit create displacement.
i open the tiff in ps, switch it to rgb and invert it vertically. in maya i make sure the imported objects feature displacement is turned off and i create displacement and subdivision stuff using the mr approximation editor. last i add a script on the displacement file's alpha offset telling it to be half of alpha gain.
ok, that seems to work fine and seems pretty easy once you get the hang of it. what i don't get, is that everyone seems to be using multi displacement 3 which seems like kind of a headache. what are the advantages of using multi displacement 3 - does it make better displacement maps?
