Hi! I am in great need of some 3DMax chess pieces,do you know some free sites where i could find some? I tried the ones from the 3DMax tutorials but i need others for different sets. Thanks for your time and effort.

Not sure if they come in separate files, but I'm sure if they don't that you could separate them yourself (assuming you own 3dsmax). If this doesn't work just use google to find some...
