I did a test with kray and trying to find a way to reduce noise. There's noise in shadows and center part of screen. I change the filter size to 1. Is that recommended? Also the other setting I don't understand much.

kray setting.


Btw kray doesn't support stereoscopic rendering Camera checkbox. This animation will be stereo. But I can do workaround by using two camera. But stereoscopic checkbox would be cool.

What render mode did you use? Looks like every frame has another photonshoot or independent FG.

This doesn't look like antialiasing problem. Did you use uncached by any case?

Btw. you can render stereo images from Kray too....
Try this command:
camera stereo,0,0,0,(0,0,0),<>,0.01,3;lwcammode 8;

0.01 is eye separation, 3 = number of stereo images (adjust to your taste)

I don't see why you use Kray for this type of scene?! That's not where Kray gives its best interest.

There's no gi in the scene. Just raytracing. I used kray because the raytracing is faster than lw renderer by almost 3 times
I could get rid of the noise in lw renderer if I use enhanced medium. Is there equivalent setting in kray for enhanced medium?

in that case increase the lights quality, I suppose it is now min 1 max 4?

yes. i have that tab set to low.

if you set qualty to low, you risc getting low quality

What is a good value. Some setting when set to medium give super long render time.
min2-max8?

kray has to get out of the archi renderer only rep.
I hate to mention vray or even mray but as anyone who uses them know it is a general renderer. Can do all ltypes of rendering from non photo, photo, effects, etc.

Kray is not archi only renderer. However Kray really excels in rendering global illumination intensive scenes and most architectural viz happens to be just that.

For now imho it is. Support for lw features to help compositing and more control for lights and object flags, exclusion, inclusion of objects,etc we can control look of scene better.

Use Lightwave's Perspective camera instead, it is much faster than the classic camera in almost all cases!

I used persp cam before with 4 AA pass no AS and its flickering. Turned up to AA 8 less filcer but longer render time. Don't know why that is but classick cam enh med no AS is pretty good.
Haven't tried to use kray with medium quality setting for area lights it might get rid of the noise.
