Black Textures in LiveViewer/Render Tweet

[phirmin1]

Hello,

i have a problem with rendering a project with Octane V3.08 RC1.1
I'm trying to render the project but the same texture does work on some parts but don't work on others.
Seems like its primary happening on Loft-Nurbes.

I uploaded a picture of this problem:

Seems like its a problem with the Octane Metal material Model "GGX". If i use the BRDF Model "Beckmann" instead, its working. Its the closest i can get to GGX look but it would be nice if GGX works too.
