John's absolutely right. Plus that reminds me I forget to say when you wrote... "I found this mech with others in a Battletech website as freebies in 3DS format". Always seek permission first from the original modeller before you distrubute. I know your intention is good, but even if simply convert from one format to another you could fall foul of copyright laws. Trust me, even an accidental ommission is no defence and no fun.

Pinky - you left the lens cap of your mind on again.
