Hi!!
I'm trying to render a ocean scene, with foam, ocean spectrum, flip simulation etc, but the render with karma_CPU shows different colors, in my case, red colors for ocean, flips and foam. This happens in H_20.
My scene is different to this, but for test the materials, light etc I've tried to render this project and I've had the same result. I attached an image.

The material are done with VEX Material builder and with karma XPU I don't have any render. I don't know if VEX material builder is not compatible with karma XPU.
