Multi-displace map and mid values

ZBrush Usage Questions
#1

Hi folks,

i need to create a plus and minus value displacement map for EIAS, i can do that no prob, but my question is about the mid value.

With EIAS black= no displacement, white = full, but what setting do i use for mid point in ZB, if its 50% the two maps would be wrong, if its 0% what happens to the minus value ?

This is frying my brain :lol:

ZBrush uses 50% gray for the mid point.

Have you tried using the Alpha Adjust Curves included with ZBrush 2 to create positive and negative displacement maps? There is more information about this in the Help system, too.

Thanks aurick,

Yes the first time i tried the curves the mid point still seemed to be gray, but i just tested this again with a much more simple displacement and the curves are giving the correct output i need, thats with the default 50% mid setting, great !
