Here is my latest attempt at realism,

messin with caustics,
anyone know a way to fake volumetrics in blender?

I was trying to use blend on alpha diagonally…

Nice image - sorry can’t help you with your query.

#3

What are caustics exactly, I’ve seen them, but could never actually work out what they are related to exactly, and didn’t Blender recently get a caustics upgrade?

#4

Caustics has to do with refraction, like accurately making a magnifying glass in blender…
in this case it’s the way the light plays with the wine, and scatters,(exterior emitting scatter)

and volumetrics is where lights scatter as they continue through a volume(think of a flashlight in Fog) or shadows continue through a volume, (like rays/shadows in water)

UPDATE
nixed teapot and added Wine bottle, fixed lighting

is there a way to create a separate color Chanel for each ray? this vector to be used for a "if ray passes through material type scatter(halo), if passes through other side don’t scatter(no halo)???
