Black Body Emission - Sampling Rate - HOW MUCH!!!???

[lassinger]

hi,

as you can see in the attachment, the light from the Black Body Emission on the Wall show a pixellike Light/Structure... too rough...

my sampling rate is about 100... it it too low? or what is the problem...?


THANKS!

Hello,

Is your light plane or mirror subdivided with more polygones than necessary ? With smooth ? This takes more samples to resolve.
Is it PMC kernel ? PMC should be used with this kind of scene with mirror and light reflexion i think.

It's just ideas, maybe i'm wrong...

This seems to look like Pathtracing.
100 samples is way not enough in this case.

Try with 500 up .

ok, thanks for tips...

it is direct lighting...

. . .

i will test several sampling rates...


Thanks!
