OTOY Forums

I open a place to post somme of my tests with Octane.
I begin with a subject than I have been working on since few weeks; it's around wood toys.
Elephnat done with Maya. Racing cars with 3dsmax.

I love the car. Your glass chair needs some more samples to get solved properly, you could try radiance trick of downsizeing http://www.refractivesoftware.com/forum ... f=21&t=878 or taking a second shots changing rrprob value for half the samples than the first one and composing them in photoshop using darker color layer for the lowest sample value render.

kubo : it's not the final version so I'm not going to cook a 4K version now.
Can you tell me more about the rrprob trick?
What are the good value to have a correct specular plastic render?

the rrprob (russian roulette probability) is the chance of a ray to bounce (you can search the forum, or check the manual for a more in depth explanation). You should leave it as default, but one side side effect of changing is that it will render a different solution for the same shot, where the fireflies and noise in glass will be in a silght different position. Hence if you comp both (or as many as you need) in photoshop or gimp or the like, and add the second layer as darker color you'll get rid of those fireflies and have a cleaner glass. The thing is that you need less samples than with a single image, you use a fair amount for the first one, then half for the second one or 1/3 for the extra 2 and so on.

Here is a little discussion about this trick http://www.refractivesoftware.com/forum ... 3&start=20

kubo : thanks for the explanation

New scene with emiters done in 2.3_4 C&C are welcome

Various renders with the same scene

cameras research same vue that in previous post with emiters
lot of noise instead of long renders (3h for 7000 s/px)

New scene; not yet finished.
I'm out of ideas for a better image
C&C are welcome

First version with sun. I was not very happy with that I prefer that one, but something is missing; I can't put the finger on. With other response extra views And the post production one that's it for now
