VrayDisplacementMod in 3dsmax ignoring texmap min/max. Please help!

BobFloss

I am trying to use a 32 bit EXR displacement that I baked out in zbrush on a mesh but no matter what values I put in the texmap min/max, say -1 and 1, it doesn't do anything.  My displacement is clipped at 0 with none of the negative displacement registering.  All that is being displaced is the information that pushes outward.

I know this shouldn't be this hard, what gives? In maya you simply add an "allow negative numbers" node or whatever.

http://www.cggallery.com/tutorials/displacement/ did you follow this guide?

Yes, that is the one I use.  The problem is that entering something into the Texmap min/max like it says in the guide doesn't do anything at all in the render.

hmm, hard to troubleshoot without the files. I remember having this issue before, and it was a problem with the object scale. -1 and 1 were the wrong values (way too high in my case). I'd try to get the true pixel values out of Nuke if possible.
