Hey,
sorry, i know its an old topic, but my problem is very similar to the problems in the topic.
I would like to postprocess water, with “transparent” volume. To do that, i do a clip (Mode Scalar), Extract Surface and Generate Normals with PBR_Water. Ray Tracing (OSPRay raycaster) is enabled with 200 Samplings per Pixel. My water looks blue and not transparent like yours.
How do i set transparent to it ?
Best regards
Kai
