Correct channels order in VrayDisplacementMOD in MAX ?

Post by chennn7 » Sat Jul 04, 2015 11:45 am

Hello everyone,
What is the relationship between the channels of the displacement maps which exported by Realflow 2014 and the VrayDisplacementMOD in Vray 2.4 in 3DSMAX ?
It seems the render result is not correct if I put the displacement maps from Realflow into the VrayDisplacementMOD in Vray 2.4 in 3DSMAX directly.
1. The order of axies of 3DSMAX is XYZ. X and Y are horizontal directions. Z is vertical direction.
2. The meaning of the channels in the displacement map from Realflow is "X and Z are horizontal directions, Y is vertical direction."

My question is,
Should I change the order of channels of VrayDisplacementMOD in the material editor ? For example,
" X in the displacement map = X in VrayDisplacementMOD "
" Y in the displacement map = Z in VrayDisplacementMOD "
" Z in the displacement map = Y in VrayDisplacementMOD "
Is The Result "XYZ change to XZY" or "XYZ change to YZX" or etc? What's the correct axies order in VrayDisplacementMOD ? Or should I invert some channel to get the correct result such as "XYZ = -XZ-Y" ?
Please tell me, much thanks.
