Mudbox displacement Problem

[contaxx]

Hi there,

i have a problem with the vray displacement modifier.

the displacment works perfect in still render, but in the moment i render animation... the first frame looks nice, but from than on, I have this holes in the geo?
i made tests with less displament (human head with wrinkles and so on, there it works just fine...)

what am i doing wrong? is it the mudbox problem or vray 3dmax 2014 bug?

my mudbox setup:


here is the maxfile + the (scaled in ps) displacmentmap out of mudbox

Thank you very much for reporting this bug - we got the same result here.
Meanwhile you could use Displacement Map from VRayMtl , it works correctly.

thanks for the reply!!

but how do i setup this to have the same amount of details?

on the big holes, is no information its just flat? i tried to color remap the exr texture (set the first value to -1)

try 3d displacement.

We have noticed that this persist only in 32bit EXR files exported from Mudbox - all other files are working correctly with VrayDisplacementMod.
Here is one example with 16-bit EXR :

I have added this bug into our system and I'll let you know when we have update about it.
