rendering time

[mirco]

Hi,
I am a very new Kray user, normally I use fprime.
But I think that the Kray quality/time relationship is excellent.
This is my first image.
is it possible to remove the suitable noises?
How can I improve the times of rendering? (4096x3072 for 36 h).
Thanks in advance whoever wanted to help me.

Can you show your settings?

You can try this:
Photons:
Reduce Global photons number to 500.000, adjust N accordingly.

FG:
Increase prerender to 100%
Decrease B/D to 0%
Add more blur if you get splotches...

Misc:
Set luminosity mode to indirect.
Set blurring rays max lower - 500 should be enough

Sampling:
Grid size 2 (for hirez you don't need much AA)
Use box, cone or lancosz filter since those are the fastest.
Try Edge absolute 0.5, relative 0.5
Normal and z 0.1

Thanks Jure,
your advices have been really precious.
The time of rendering he is now of 4 hours

I must only attenuate the grain effect.
