hi,
i have problems dispalying displacement maps in maya. here is my workflow (Maya 2009 and Zbrush 3.5)
1. I created a tree mesh in Maya and unwrapped the UV's.

2.Import to Zbrush, sculpt details and create a 2048x2048 displacement map from SDiv1 with these settings:

(Although Adaptive is unchecked in the image, I always have it checked. Just for the demonstration purposes, i forgot to check it.)
I convert the .tif then to .map format.
3.Export Sdiv1 mesh as an Obj and import to Maya. Turn off Feature Displacement, create mental raydisplaceapprox1 and set N divisions to 4, then new shader, plug in a displacement nodea and from there a filenode with the .map texture. after that, in the file node attributes, i go to color balance, and change Alpha Gain to 2.2 and Alpha Offset to -1.1. then, I smooth mesh my object (division levels 2, continuety 1) and click render. this is how it looks:

Of course, since my model has to different UV areas, i created two displacement maps and two different shaders and applied each to the corresponding faces.
What did I do wrong?
