@Takai thanks, i'll rest it for some time now and then back again :) @AlecMoody i sent you a zipped folder with all files. inside handplane i first tried the maya2013/14 settings but the unity settings gave me the better result. only this screw didn't work as supposed.
@AlecMoody i tried the baker, wow this is a fast one O.O it's a little bit annoying, when you try to find the right ray-offset on the first page, to always switch to the third one to press the bake-button. it would be better to have a fixed positioned bake-button. is there a possibility for an object-id pass? maybe this…
