Nasty dots filling the rendering in certain areas

[arian.mares]

Hello,
I'm new with octane and there is no manual I can learn this software from so I have to rely almost exclusively on video tutorials and forums.
Whenever I'm using emitters in directlighting mode I get certain "unbaked" areas. such as the example posted. Can you please explain what do I have to correct?
Many thanks!

You mean the white pixels?
I would try to simplify the emitter, best to use only a single plane.
Look that the emitters aren´t cut any other polygon so they are fully outside.
Play with the samplerate in the emitter settings.
And if nothing helps, try to increase the max samples.

It looks like there is a small emitter above the table, it is probably this emitter that is not sampled adequately. Does the noise improve if you increase sample_rate for this emitter?

I can't draw a single plane with this software... yeah, the emitter has volume. I'll assign a different material on one side alone and this is it. As for the samples, I stopped the rendering at about 6000 samples which is a lot even for this resolution.


Thank you kindly for your prompt help. I will keep you informed with the progress I made.
