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)
path.hybridbackforward.glossinessthreshold = 0.89999997615814209
sampler.metropolis.largesteprate = 0.40000000000000002
sampler.metropolis.maxconsecutivereject = 32768
sampler.metropolis.imagemutationrate = 0.10000000000000001
renderengine.type = "PATHCPU"
sampler.type = "METROPOLIS"
lightstrategy.type = "POWER"
path.photongi.photon.maxcount = 320000000
path.photongi.photon.maxdepth = 16
path.photongi.indirect.enabled = 1
path.photongi.indirect.maxsize = 0
path.photongi.indirect.haltthreshold = 1
path.photongi.indirect.lookup.radius = 0.05000000074505806
path.photongi.indirect.lookup.normalangle = 9.9999997090929202
path.photongi.indirect.glossinessusagethreshold = 0.5
path.photongi.indirect.usagethresholdscale = 1
path.photongi.caustic.enabled = 1
path.photongi.caustic.maxsize = 6400000
path.photongi.caustic.lookup.radius = 0.004999999888241291
path.photongi.caustic.lookup.normalangle = 9.9999997090929202
path.photongi.caustic.updatespp = 1
path.photongi.caustic.updatespp.radiusreduction = 0.995
path.photongi.caustic.updatespp.minradius = 0.0024999999441206455
path.photongi.persistent.file = ""

Can you share this scene? Looks really good.
