Vray 3.0 - Zbrush Vector displacement map

#1

Anyone know how to set vector displacement map from Zbrush to Vray? I can’t get same result as in Zbrush

#2

are you using vray subdivision method or using polysmooth?

#3

Well, This is how I tried step by step:
In maya I created cube and exported it to OBJ.

In ZBrush I subdivided it and made simple shape. Then I created vector displacement map.

In maya I imported obj file. Added vray attributes (subdivision) and material.
You can see details in attached file.

I tried “Ear.exr” texture from Arnold Vector Displacement in Maya Vray and it works correctly.

#5

Did you set tangent flip/switch correctly? See http://docs.pixologic.com/user-guide/3d-modeling/exporting-your-model/vector-displacement-maps/ (scroll down to “Diagnostic File for the Perfect Export Settings”)

#6

I made Zbrush diagnostic vector disp.file. You can see result render in attached file. I don’t see perfect sphere :banghead:
