best settings for interior night shots with emitters
Posted: Mon Sep 05, 2011 9:07 am
Hi!
I have serarched and read here and there but still cannot get a decent solution for this... so here I am asking if there's some further trick to avoid huge hotpixels/firefly in night interior scenes with emitters.
I apologize for what is probably the n-th thread on this subject and the lack of image (it's a WIP for a client I cannot show at the moment.
scene: a simple interior with a dining table with chairs and stuff (not too much). 3 hanging lights (emitters) and 3 emitting cubes laying on the table (as they were candle lights). the room is wide open, i.e. I have floor, ceiling and back wall with the other 3 walls missing.
environment: I tried both with a floattexture with very low powre and daylight at 22pm
materials: I removed any unnecessary glossy and bumpmap, there's no glass
emitters: texture emission using a kind of softbox image with shaded borders. I tried a bunch of combination of power, etc. at no avail (usually I'm able to get a decent result playing with these values but not in absence of a proper env light as now). I also tried with IES but I can't say I totally get how they work in Octane yet (saw the video tutorial, simply cannot see how different settings change the light in the scene)
kernel: tried both PT and PMC
hotpixel: removal set to 0 (usually I don't need to go that low...)
thanks for any advice, just a newbie in Octane yet...
cheers,
Alessandro
