maya 2009 / zbrush displacement issue - not the usual!

Can somebody please take a look at this post (I didn’t want to double post) http://www.zbrushcentral.com/zbc/showpost.php?p=586145&postcount=208
and give me some insight as to what I am doing wrong? This is driving me crazy.

Thanks!

Actually the mental ray preferences mentioned above did the trick for me. so ignore my post.
