help, what are these funny colored dots come from ?!
SL is around 20... what a great result for paying 160 € to the renderfarm

What kind of materials do you have in the scene? Are you using any SSS materials? It also looks like you are using about 25 multi light sliders which add a lot to the memory usage. You could merge some emitter geometry that are ment to have the same strength. It would help a lot if you could do a Pack & Go for this scene for debugging, send me a PM with a link to it or an email. The files will remain private.

My guess...it's Multilight.
I had a pretty simular problem a couple of weeks ago. The image size was 1024x768 with SL 14. The difference is that a had an effect of colored-noise all over the image. You gotta use less lights in 'multilight' or group/connect simular lights into a single light object. That helped me at least. How many lights do you have in 'Multilight' tab? As far as I see, it's about 30 - that's way too much.
BTW, you can fix the problem with PS in an hour or so. Another way is to render waaaaay too looooonger.

One more thing - this sort of things happen also when you use 'full .ior'-mode or especially when 'Dispersion' is enabled. Did you use any of these?

I encounted the same some time ago. Like Mihai said, merge all lights with same intancities to reduce the memory usage.
First of all, load back the mxi of the rendered scene and find out by switching on/off one by one of these lights which one/s is/are causing this issue.
In my cast, i deleted it and re-export the geometry in studio to do the emiter again and it work good.
You know shit happens...hope that help.

I had some dots with, caused by emitters (emitter material on a pailn),
using cinema-lights sloved the problem...
All the best,
Andre

thank you for the responses.
i have eliminated the noise in fotoshop.
one reason, the scene has so many emitters, is that i wanted to have colored rgb lighting in the scene, so i copied some emitters 3 times to mix them together for different lighting moods afterwards... (they don't intersect each other ...)
no sss, maybe too strong reflecting materials like the floor and the metals...
i will send a packandgo file to mihai thanks!
