Just some objects to cast shadows....

can you help me?

Hi, nico. Yes i tired to mimic "studio" light setup, so it has nothing to do with natural lighting. There's screenshot of this scene:

Quick test.

very good example that art thrives in economic downturns.
Maybe this year I can improve a lot too

:)
Yes, i have Kray for more than a half of year, but never had enough of time to put hand on it until recently...

done I was just wondering, any reason to use this instead of the built in occlusion nodes? I dont have access to the IFW nodes so i was wondering if it was something worth looking into? I think there's no big reason to use IFW occlusion, i just found out it renders faster when "Dissolve" ...

Looks good to me, but in addition to comments, i would add refraction to table's glass and looks like there are smoothing problems on metalic surfaces like drawer handles and table frame. Reflections look weird. Try to reduce smoothing angle, if it won't help you can try to break geometry apart. Lik...

Few guys asked for setting and i didn't answer anyhting that may help.So I tried to describe what i learned from my short Kray experience. Please note that there are probably better ways to do things, i just don't know them yet :) So take it sceptical. Most of tips look obvious and most of it i dig ...

Thanks for comments :) iblagdan how did you go about that wear and dirt on the edges, painting on UVs in PS or some other means? Yes i had to paint texture in Photoshop over UV layout. Looks like no edge detecting nodes works in Kray. jdomingo leftover, would you be able to share your technique on p...

There's a couple of Kray tests i've done for last 2 weeks. Thanks to crisis

In Quality tab try to change Recurse Min/Max to 1/4, 1/3 or maybe even to 1/2 and see what will happen, as well you might try lower Area light threshold treshold

I used low N to make spots more noticeable. And yes that's what i was talking about, objects close to light cause this problem. Setting Intensity falloff to Inverse Distance^1 helps as well.

I made simple test scene for you. Do 2-3 renders and you will get some of these splotches. Im sure they related to "heavy" lit surfaces close to light.

No it's not related to Photonmap problem:) Looks like very high energy photons get bounced from objects that are close to light. Reducing light intensity near a light source by changing it's falloff to inv. dist^1 instead of inv. dist^2 helps to get rid of splotches or at least reduce their number d...

Is using Photon Number Multiplier for lights has any meaning when using Lightmap mode? Im getting 1-2 bright spots quite often when using Lightmap mode. They looks like "lost" high power photons. Can't track down what causes these, so i have to re-render image few times untill these spots ...

Okey, thanks. I think it would be good to have one.
But seems like my problems are caused by some bug. I left a msg in Bug Hunting section.
