Chess scene, 50000 samples, 3 hours!!!

[yzaroui]

Here is my last render on my gtx 470.
I got some caustics with 120 ray depth pathtracing! Took 3 hours 15

Very nice.

Would like look different though on let's say 12ray depth, and only 10 000 samples ?

[yzaroui]

Here is the same render at 45 minutes (about 15000 samples).
No very big difference.

GeorgoSK, I tried as you said : 10000 samples + 12 ray depth.
Took 42 minutes.
12 depth is same as 120
But 10000 samples are not enough. Image is very grainy

[GeorgoSK]

haha, thanks for testing, good comparison !

hmmm,
i am wondering that the pictures in render sequence would brighter.

any clues why this happens.

That's nice, what kind of camera do you have?

[yzaroui]

I will tell you about the camera later.

For the environment I used the ennis.hdr from here : http://gl.ict.usc.edu/Data/HighResProbes/

Enjoy Octaning
