Any hardcore Zbrush to XSI users out there? I need some additional info
on using displacement maps from Zbrush in XSI's rendertree. What I've
found on the various forums isn't quite what I'm looking for. Here's
what I'm having problems with:
1. There seems to be a few important steps setting up sub-ds in Zbrush
for proper export to XSI. I can't seem to find any reliable explanation
of these variables and why they are necessary. Things like "store a
morph target", "turning on SUV or smooth UV", "switching morph targets",
etc.
2. Is there any mathematically correct way to convert Zbrush's 16bit
grayscale map to something that MR can accurately duplicate? I've done
everything I've found available on the web like converting to 16bit TIF,
flipping the image and using scalar math nodes in the render tree but
the results are not that great and the mesh seems to always puff out or
shrink in a bit. Just seems too much like a guessing game. I would
imagine there's a more accurate method.
Thanks for any tips/tricks anyone can provide.
Kris
