btw i wanted to mention seemless modeling is a GOOD idea for u modelers out there and i suggest u learn it. it has many beneifits cause remeber that game engine renderers are very poor compared to model program renderers like max. what might look good in max will look horrible in game. seem less models help discourage Z-fighting, help with making clean smoothing groups, and it defines merging shapes much better.
for u kitbashers, parts form seamless modeles can always be made. and with a little modeling skill u can take parts and make them into a seamless mdoel too by leanrign how the bring objects together and remaping UV coordinates.
good luck all.
