32 bits DISP ZBrush to mari doesn't work


Hello, I’m new to mari and I am trying to import my displacement map from zbrush to mari, is a 32 bits .exr displacement and it works well in maya but I don’t know what I need to do in mari to see it well.

What i do:

  1. I import the disp that it works well in maya to the layer in mari
  2. I create a blinn shader in mari and connect the disp to the displacement layer.
    I tried to touch the disp values but nothing

can you help me?
