problems with rendering displacement maps from Z brush

[system]

Hi there.
I have this problem: I imported a UV mapped mesh into Z Brush ant sculpted, then I extracted and exported displacement maps and tried to map them on to the mesh in Maya 2008. I assigned mental ray DisplaceApproximation node to the poly mesh with approx method set to parametric. After I rendered the scene, displaced mesh seemed as if every face of the mesh was shrinked and disconnected from adjacentfaces. There were gaps between faces. Is this a problem of a displacement map, or an approximation node settings, or some problem with the mesh itself? How can I fix this?
Thank you for an advice.

I’m having difficulty finding clear step by step information on creating Displacement maps/Maya integration, but I saw a brief tutorial by Scott Spencer that showed how exporting the file as a .ma into Maya automatically set up the node connections. He also has a tutorial on pasting a script for Displacement maps into Maya. I hope this helps, and if anyone can direct me to additional current 3.2 information for creating Displacement maps for Maya, please post them. I’m curious why this information is not clearly offered by Pixologic

thank you
