Every time I try to do anything with the specular power slot in the UDK material editor my model turns black or I get very bizzare shading. I tried a dark image, a light image, simply using and adjusting a constant and its always messed up.

Are there any examples of propper use of spec power or anything I need to know that's specific to UDK?

My gloss setup works fine in max with the 3point shader.
