Iray 1.42 doesn't render correctly the new hair system

Hello,

I keep the default model used when I opened Character Creator.
I added the new air system, I took the second(short hair) in the pack I bought.

When I rendered with CC3 result is good, when I rendered with IRay, the result is not good as IRay didn't take care about the color of the air and also the based of the air is rendered in ugly way even if in the parameter of the texture of the hair base I put opacity to 0%.

OS: Windows 10

Hi Lianchiu,

But the color problem is also in CC3, is it normal that a Reallusion plugin doesn't work correctly with Reallusion product???

To be honest I did not bought iRay plugin if I know that it doesn't support correctly all features in Reallusion product.

Hi Lianchu,

Thank you for your hint, effectivelly it resolved the scalp problem, but I still have the trouble with the hair color.

And for your information, when I export the model in nVidia Omniverse I had the same scalp and color problem.

With other hairs, legacy one, everything, color and scalp work perfectly.

Check this known issue

iray doesn't support vertex color that's why the color looks wrong. but it's expect result.
