You have any bump map set to wall material?

But unfortunatelly no effect.
Hot pixels pop up in the same places..

Thanks Aoktar!
Your scene shows some hot pixels in the beginning but they are lost in time, giving clean image in the end...
I'm going through your scene to figure out what I screwed up with. It's a good lesson
Thank you

I noticed the sample rate on all his lights were at 1. Is that it? Do please pass on any info you glean...

ok
I started using proper scaling, so what's 100cm in real life is 100cm in C4D.
Now I don't have to give each light 20'000 power.. Now 100 or 200 is enough in most cases.
The way of mounting the light is different. I used some torus to give the light proper modulation. Now I just use extrude inner, and extrude so the light is in some sort of "tube" inside the ceiling.
I'm using light sampling at "1" value. No idea if it changes anything, but it doesn't hurt too
Honestly - in every new scene the hotpixels dissapeared...
Below the "straight-from-C4D" image after small color correction (no other retouch).
I'm rendering the pmc/5 shot now, but it will take next 5hrs cuz I'm willing to give it a downscale.
Seams like the scene sizes were an issue....
So thanks to iFloris for giving a good hint.
cheers!
PS: below is DL/diffuse, 6/6 / diffusedepth:3. maxsamples:4000

PMC/5 maxdepth: 10'000
hotpixel value: 1
no downscale, "straight-from-c4d" image
NO NOISE!!
thanks guys!
