Grainy Geo Lights?

Recommended Posts

Hi all,

I'm trying to use a geometry light to light up a vdb, but I keep getting a grainy texture on my toon shader/material and can't seem to figure out why. If I use a regular point light, I get the desired result, any ideas on what this could be? Thanks for the help!

Need more info. What geo are you using for the geo light? Where is it? 

Lights that use area to cast illumination, as opposed to a single point, are inherently noisy ; what are your render settings? It sure looks like they're low-quality.
