Ok...uncle. I have had trouble getting displacement maps to work correctly w/ image maps. Procedurals  seem to work, but I have tried quite a few things. Anybody else noticing problems here? Here is an example. This is a normal map used as bump...works fine. However, I have gotten displacement in the past, but looks horrible so then I tried some sub-d options...no help. Now I can't get anything to show. The render is the bump, but the dismap is showing in back. Enable and displace in 3d view are enabled. I turned off bump also...nada. Kinda wanta know if there might be some bugs? I used the same dis map in D|S for displacement...works fine. Don't see anything wrong with map anyway.

No need to think outside the box....
