zbrush 3.1 displacement map in poser

[system]

hello. i have been using zbrush 3.1 for 2 weeks now and its amazing.

i used the search function and i didnt find out an answer. i made a displacement map for my poser figure. poser doesnt read black,grey and white for displacement maps. so we need to subtract 0.5 with nodes.
the problem that i have now is that the middle grey in poser is not the same grey in the zbrush displacement map. i looked in photoshop and its not the same. so am i doing something wrong or what?

thanks for help

Though this isn’t what you asked for…it is a complete tutorial for the pipeline between Poser and Zbrush.
