Hey! I am trying to use the vray mix node with CUDA/RTX, but I can't seem to get it working. It works fine when using the CPU and also with CUDA/RTX when I have a very simple material network, but for larger matnets it just outputs black when using CUDA/RTX. If I take the inputs to the mix node and output them as the base color of the surface material, then I can see the inputs are all perfectly fine, but the output of the mix node is still black. I recreated the mix node using OSL, but it gave the same output. Any help would be greatly appreciated! Please let me know if I can give more information.
