Hi there,
I have been searching and trying heaps of things out but I can’t figure out how to get this right. There must be some logic to it instead of just guesswork.
The thing is, when I export a displacement tiff from zbrush to XSI, i can’t for the life of me get the mid level right. The displacement is always pushing in or out.

How do I figure out wht to set the ‘Change range’ node to, to make it right?
any help would be great 
thanks
Pete
