I have a big problem, this image take 1 day and 7 h of render time and I don't know why.
There are 1 distant light (sun), 1 arealight (the window on the left), a skydome (100% luminosity) and the 3 light (300% luminosity) on the bar zone.

Help me please!

Hmm from this file I can't realy say what is wrong except that B/D is set way too high which is probably causing long render times. Kray only saves Photon tab and FG settings to file...

Could you post your .lws file so I can take a look at all the settings?

Here is the .lws

As I said turn down B/D to 50% or 100%...
Sthocastic AA is slow. Try grid 3 or 4 full screen AA.
Also turno off "FG reflections".

You can also try lighting with a skydome instead of Area light...

Ok, tomorrow I'll try it.

Thanx Jure!

Litle TIP#1:
Use in "Image World" HDRI map! (100% brightnes max)
In "Image editor" - "Processing Add filter" use HDR Expose (white point 1.0, and black point 10-30%)
Send you my best HDRi map.

Litle TIP#2
To increse blue color of GI in "Image editor" - "Editing" use Saturation max (0.5-1.0) on the HDRi map

Hi Johny, thanx for tips and the image, you think to use only Hdri image or Hdri+arealight?

pienri · Post by **pienri** » Fri May 19, 2006 10:58 am

Here is the render with Jure tips (but I don't delete arealight) 6h 15m!
Next render with Johny_Quick tips!

Thanx

I use combo: HDRi+Area light+sun distant.
Use in Tailer command: "recurse 10;" to limit bounce light. Dont use recurse 1-9! - this destroyed bounce in glass (black colors on the glass). Recurse 10 is very good.

another render, time: 6h. (jure setup + arealight)

Why is the render looking a bit noisy?
Those render times can be improved IMHO. Can you post your settings and your precomputed render?

Hi Jure, escuse me for long silence time, but I have to work hard for other projects.
The settings are the same I posted, but I turn down B/D to 100% and grid 3 full screen AA like you suggest to me.
The noise on the last image is for the postprocess, the original render is clear. How can I improve render time?

Thanx
