Does anyone have any info on small lights. No matter what I do i get this - noise I dont even know how can we use small lights in octane. Please otoy can you make small lights as fast and smooth as daylight system
thank you

You could try hotpixel removal for the bright pixels and up the lights sampling rate.

set gi_clamp between 0-1

thanks
i cannot find it. We only use AO because it is for animations I guess only path trace has it

yes, it's faster than diffuse mode of AO..

Different modes of the DL kernel mostly affect indirect lighting, but reflections, scene lights, refractions, do not change. Sometimes PT will work faster or PMC because it can focus on the reflections the most instead of wasting tons of samples in the simple lighting solutions.
Anyway a good solution to your problem is to increase light samples for those lights. Go to the Emissive node on the lights you need more samples for, and go down to the bottom and it should say something about importance and its default value is 1.0, try increasing this to 100 and just see what happens. You can mess with it from there.

i hear Karba said somewhere increasing samples takes other samples away from other parts. I will try.
I wish there lights were as fast as daylight sun
