I can't figure out how to do displacement in Maya. I've got everything set up with a displacement map attached to the shader in the Displacement Mat. I've tried using Feature Displacement, and I've tried tesselating my object to make lots of polys to displace. Nothing seems to work. Is there a way to set the strength of the displacment like you would set Bump depth for a bump map? All I can find is the Displacement vlaue, but you can't put a number in there as it's driven by the grayscale map.

HELP! What's wrong here?
