@Salvador Jimenez: tnx! I know what means this option Anyway: I use 0,01 for final and 0,02 for preview render.
@Bruce Hart: tnx! pls can you explain (maybe with an image) what is "noise" on Light Cache?
@Juraj Talcik: tnx, I understood that Light Cache is so fast to calculate. So, also 2500-3000 subs don't scare me so much
Anyway, to all:
new question:
how Light Cache (his rays) works on these 2 situations?
- Light Cache only for primary bounce (none on secondary)
- Light Cache both primary and secondary bounce.
tnx!
