Description

From left: skimmed milk, chardonnay, merlot. One single light from the top. Ten minutes to set up the scene. 24 hours of rendering (!) with the (wonderful) INDIGO renderer www.indigorenderer.com Note that the scattering and absorption parameters are physically correct, taken from literature.

24h!!! That's a long time!!! I think you can do shorter with AI :) Anyway, great realism!!! I'll make the glass a little tinner. B->

Well, 24h its long, but the PC was working, not me! :) What I mean, is that I am sure I could have spent one week on this image with AI without obtaining the same level of realism. Its true I am not a pro, anyway.

24 hours? Far too long for any render IMO and still too much noise. Nice try though.

i cant argue render times since I have had some over several DAYS for one image. Your effort is great. Lots of artifacting but it happens. Try Vray. speeds are MUCH better. Nice work! -chachi

The dots you see should not be artifacts. The point with this unbiased rendereres is exactly that they claim to be artifact-free. What you are looking is the noise which gradually decreases as you let the renderer calculate (you can stop it when you want, there is no "end"). Now, I know Vray and I think its really amazing ad fast (see my previous image posted), but the point is -as far as I know- there is no way to plug the real physical parameters of a material in a biased renderer. Or is there? Here I took absorption and scattering parameters from literature, plug them in and voilà. I need this capability for an ongiong work.

Stick with a true unbiased render engine such as Indigo (or one of the commercial offerings) - as hardware becomes more powerful these render engines will become the norm. I remember when ray traced engines used to take more than a day to render a small image! With the image it looks like you wish to display Indigos' SSS materials - fair enough but the scene composition looks rushed and as already mentioned the glass looks too thick.
