Cropping Materials in UnrealED3

[YakZSmelk]

I created an environment in 3ds max and some of the objects I used share texture sheets. I'm wondering how I can crop a texture sheet within Unreal so I can use a specific area of the texture to tile in the environment.

BTW I have a strict number of texture sheets I can use so I cannot just make a new one.

I don't think it's possible to tile only a part of a texture with the options available in Unreal Engine 2.The only way to achieve a similar effect would be to tile multiple surfaces and align the texture on each one separately so only that part you want is visible. I can imagine bad things going on when mipmapping kicks in, though.
