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?

[kubo]

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.

C&C are welcome

[gzavye]

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)

[gzavye]

I'm out of ideas for a better image

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.
