Problem

Description:

hi,

wanted to finally render my shots and realized that there is a big transparency issue in the Vray production renderer vs ipr on the entire hair regions, especially at the root. When I try to render for production, no matter if I use light cache or brute force, even with highest settings I have this transparency problem that looks very awkward. I also tried CPU and GPU, both produced this issues. IPR luckily does not, it looks as expected - is this an issue related to Ornatrix or Vray? The problem is that I obviously cannot render my final shots with ipr... I have no clue how to solve this and like this I cannot render, I can see on the roots through all the hair and discover the layers below.

 

any urgent help is highly welcome

Steps to Reproduce:

Btw: I am using Vray Next with the new next hair shader. Attached the image that show the differences.

Here are the images that show the differences (Look at the roots)

Hello,

This is strange. What exact build of Ornatrix and Vray are you using?

Hi there,

 

Using the latest official ornatrix build (18194) with Vray Next (v04.04.2) and Maya 2018.3

I noticed that it's happening with the new Vray Next hair shader only. If I use the former Vray Hair3 MTL shader, all is as it should be.

 

KR,
Axel

Thank you for the details, I will check if this issue is in our side, if that is not the case I will contact Chaos.
