Custom model textures not working properly

Recently in my modeling endeavors, I made my first buildings (yay), but when I put them in game the buildings are all grey, except for the few places I UV mapped.

The grey areas are where I used the repeating textures in blender. When I rendered it in blender it looked perfect, but now it's just broken. Does torque 3d not support repeating textures on materials, or did I just do something wrong in blender? I'd really like some help on this, so input is greatly appreciated.
