Thanks for answering.....maybe their wasn't much of chioces for me....I have heard that maya have the extra Plug-in which is licensed by Alias....you gotta buy from the company and it was quite expensive....so if you are not the game company ,it maybe too hard for you to get that.....Fortunatly we still got .X Plug-In....even it can't cover all the subject we want.. but it is better than you havn't got any of it....T-T
