Realistic Glass Shader
I have many fireflies in my scene. Can I reduce them?
Yes, try to turn off reflective and refractive caustics under the light path settings. The shader has built in caustics and does not depend on the cycles caustics.
Does it work with 3.2+?
Yes, with the latest version for 3.2+ you will have a slider to control the amount of internal caustics you want to have in your scene.
If you want to use internal caustics make sure to have them activated in your render settings (light path), on your casting object and your receiving object.
