Users errors?

5 hours? where?

Dont fool me
Yes there been some long renders times

I think you forgot this is the kray forum, we render animations in 5 hours ;P

the difference of rendertimes is probably because each scene has different light and surface settings and the more simple the scene becomes by surface and lighting tweaking the lower quality settings kray requires in order to produce a nice and smooth image.
the rendertimes may differ but each render also looks completely different.

ooo
This all looks complicated, so much settings......
Do you have an in-depth manual, tutorials that new users can get into and learn from the ground up?

G. is working on an in-depth manual... But writing manual is not his strongest point unlike coding .

But anyways in 1.7 you have presets so you just choose quality and fire away.

wow AMAZING quality and render times !!

I am so happy that Kray got so much attention on the NT forum !! hope it translates to more sales and more development !

I think this IS the render engine to beat !

congrats to you all

Matt -

thanks for posting the scene erwin. my version took 16 min. with 9.2 and i was wondering why your scene rendered so much faster. the glas on the shelf takes forever in my scene.

here is my version.

for frost_glasses - remove Refraction blurring, set Bump (3mm,3mm,3mm, Turbulence) and give the same result, but much faster.

I've tried tweaking those settings and the grain does indeed reduce. Neat.

While I'm on the subject, what does the Luminosity threshold setting relate to? If it set it higher or lower, will it also affect grain?

Whenever you see "threshold" in Kray interface it always means the same:

Threshold defines the how much difference of two pixels is "allowed". If difference is greater than that defined by threshold, Kray will increase rays, untill the difference gets smaller than the threshold. But it will also stop adding rays when if it reaches "max" rays even if the difference is still greater than threshold.

Hope that's clear.

Yup, very clear. Thanks Jure.

Yes this is problem. I worked on version with standart system renders....
This is version comare to V-ray with: backgrund color, Exponential parametr 1.0 , Multiplier 1.0 only tweak B/D Multiplier

vray get more quality reflect_blurring (see floor near window)
How it does?!

I'm not sure it's of a better quality, there is just more reflection blurring than the kray version.
