Can you render out an whole animation with tone maping settings or this would be a problem adjusting every frame?

Sure can! And I'll do it as soon as I have some time...

Jure I saw your animation in the gallery.
I must say that Im very inpressed with Krays quality and tha fact that your probably the only rendering engine that put its animation online, is pretty impresive!
How much did it take to render the whole animation and on wich computer?

Those animations are made by some other fellow beta testers. Most of them ave render times shown in them and are rendered on older (=slower) versions of KRay.
Anyways Kray has alot more to show we're just waiting for more users to join Kray community and start posting their own work!

Correct me if Im wrong, but when rendering an animation in Kray, the first frame takes the longest time to finish, right?
How is this tecnique called?
Frames after take less and less?
Is that correct?

Since Kray already have shoot all needed photons and Finalgather rays in the first frame it only needs to shoot extra rays if any, for the following frames.
What it's called: Radiositycache saved to file. Vray and others also have this technique

Jure do you know on wich computer did the man renderd out animation (from your model), and how much time did it take?
Im very impressed with your animation gallery :)
As i said eearlier, first time I see some render engine uploading animatio files for others to see, and lets not forget rendered by user, NOT studios!

Check here Mario:

first frame 5m25, other 199 frames about50 secs each...

Very impresive timing!
If added 2 more CPUs it would come down around 30 sec if not even less.
But what abouth more complex scene, like the "messy" room, wich is far achived realism in animation that I ever saw, what are the times there?
Any information maybe?

Silver said that that HowardB room rendered in about 30min per frame but he doesn't remember if it was on his old or his new computer. :)

Anyways it's fast!

If thats on just one CPU then its o.k.
30 min for one frame, ughhh :?
Well, but if I think of Maxwell then its :P

Mario, dont laugh at my modelling skills...;)
By using luminosity 2% on these spheres and amplifying the photonmultiplier to 100 i could light the whole room without getting burnouts. I also used Exponential 90 + hsv. Another benefit of upping the photonmultiplier and exponential instead of amplifying the lights is that it renders much faster and dont require so much FG to get it splotchfree.

Silverlw I dont get it?! :roll:
What do you mean?

You asked about tonemapping before and the image above uses tonemapping to get it lit in that way + that it renders very fast. Here is a more serious scene but with the same basic setup. I used photonmapping multiplier 1.0 (standard) but since the outside hdri was very dark i increased exponential to 100 to get this endresult in 25 minutes.

Seems to me that Ill be waiting for you training DVD :)
Do you maybe plan some?
Sorry for this questions its just taht I never used Vray, Maxwell, so all that sampling, tone mapping your reffering, are quite new to me. :cry:
Im still rocking with Lightscape, but I have my eye on Kray since I also used Lightwave a lot before, but left it because its GI was so slow.
