Thanks all. I had is basically right but I didn’t have the ramp in there. But it’s still not working. I wonder if it’s a Mac thing. If I create my mat network in /mat RSNoise > RSRamp > Redshift Material and pipe in the Redshift Material into the Tint Shader in the Render ROP, I see the volumetric effect but no noise. If I instead build vopnet and plug that in, I completely lose the volumetric effect of the light.
