But currently you can have good looking juice without caustic cache or light tracing and even with rough glass. it is working in any light condition or engine mod (Bidir and Path )

Classic BiDir might work, i tested the BiDirVM and caustic cache, they were very slow on huge scene with 40m pool and 0.1m juice glass.
But seems like i have working settings now:

Code: Select all

path.russianroulette.depth = 3
path.russianroulette.cap = 0.5
path.pathdepth.total = 17
path.pathdepth.diffuse = 17
path.pathdepth.glossy = 17
path.pathdepth.specular = 16
path.hybridbackforward.enable = 1
path.hybridbackforward.partition = 0.94999999999999996 (inverted in Blender)

sampler.metropolis.imagemutationrate = 0.10000000000000001
renderengine.type = "PATHCPU"
sampler.type = "METROPOLIS"
lightstrategy.type = "POWER"
path.photongi.photon.maxcount = 320000000

Can you share this scene? Looks really good.
