Transparent plastic cover box - caustics
Posted: Sun Sep 25, 2016 11:12 am
Hello! 
Resolution screen: 1680x1050
Render time: 80h52min running my EVGA GeForce GTX 980 Ti SC+ w/ Blackplate
NOTE: sorry for few noises but you aren't worried and it's normal because the real-life is extremely hard for caustics.
Using Octane Render ONLY v2.25 because I don't like from v3.00 to v3.03.4 or to v3.0x due the caustics later issue.
Render PMC kernel settings with all defaults except:
- 190,095 spp (samples per pixel)
- 60 diffuse and 115 specular depthes
- no "caustic blur"
- 10k-reject
- parallelism 1
Specular material settings for transparent plastic cover box:
- reflection 0.94
- transmission 1.000
- index of refraction 1.43
- dispersion 0.005
- uncheck "fake shadows"
- rest defaults
This scene is based in OctaneBench but I've corrected the few bad specular settings for cover box, I've turned off light areas and I've changed to daylight as our sun environment - do you remember this?
Do you like this screenshot?
