Imported .OBJ doens't light up


I was wondering; Why is the de-polymized OBJ of a terrain not picking up any light? I've textured it, loaded my UWV map, but no matter how much lights I put on it, it doesn't seem to light up, while the original terrain next to it does take light..

Anybody any idea?

Thanks in advance!

This was total n00bish on my fault.. Fixed it by baking the texture into the OBJ in 3dsMax, before exporting as a FBX.. Learn everyday!
