I have have recentlly made a move from lightwave to zbrush in order to improve my character in particular clothing. What i was looking for was the ability to sculpt cloth folds. I have searched high and low for good tuts which would make me understand how to achieve this. I came across your method here http://boards.polycount.net/showthread.php?t=43052 and damn I think this may work for me.
The challege today is to cut up some cloth folds and follow you instructions, I just hope you don't mind me dropping you newbie e-mails if i get stuck.
