Displacement from ZBrush

[illuMinator]

Hi all,

 
I am trying to use a displacement map, that was exported from ZBrush, on a Mantra Surface material. The map from ZBrush works when I use it with Maya and Vray, but something goes wrong with Mantra. I don't know what I am doing wrong here.
 
Here is the result with Vray (how it is supposed to look like):
 

 
And here the result with Mantra (notice, for example, the problems on the upper lip):
 
 
 
This is the Mantra Surface Shader displacement setup:
 
 
 
The displacement map is 32bit with mid displacement at 0 and smooth uvs is enabled.
 
Any help is much appreciated!

Well that was weird. I set the Displacement map back to Luminance and it worked. I tried that already exessively this morning and it gave me horrible results. Obviously I had something wrong there...
