Roger, whats up with the sudden white color "boost" (chairs and kitchen parts)?
If its not a problem can you try doing animation without bllury reflection on the floor and compare the timing with the blured one.
Like the overall feel!
Superb render quality!

edit: One thing I also noticed, last one second your camera is static but parts with glossy reflections are heavily flickering (not an natural behavior)
Any chance to fix that?

the colorboost... I really dont know why there's a radiosity flicker there...
the overall rendertime on this animation was 23 min. on a dualcore 4200+ AMD
but it could speed up really good if i have removed the glass wall...

I'm testing un-blurred ref. parquette now...

The color boost is most probably because Roger rendered first couple of frames with different GI file (or without GI file).
The thing is that when you save your GI file and use Both all frames will pump irradiance data out of this file. And when you change your GI file irradiance is calculated all over again and because of the nature of biased GI method, no two irradiances will ever look the same...

So when you render out animations make sure you don't change your saved GI file.

Thanx for the tip Jure.
Roger, waithing for the results

the wierd thing is that a frame wiyh reflective parquette takes 22 mins
and blurred takes 20 mins?

Hehe. That's because Kray uses certain optimizations to make blurry reflections faster. You probably have blurring accuracy limit set to 1%. This speeds up blurry reflections alot because Kray uses only irradiance (and not FG) for computing reflective surfaces that have blurring amount > 1%.

You could make bluring accuracy limit 0% which means Kray will use only irradiance for all reflective surfaces, even those without blurring. But this way you risk having your reflection look wrong.

So what, in Kray blurry reflections render faster then nonblurry?!
You might wanna put that as an advertisment

I hope to be able to make such an animation quickly

20 minutes for 7 second of animation is VERY GOOD timing, and only on one dual computer!
Add one more thats 10 minutes for 7 seconds, with blurry reflections.
Very impressive!

we have a farm on 20 cpu's so I REALLY want one of those kray.exe to put in my ButterflyNetRender soon as possibly thanks
