A little sub-surface scattering... Long render, slow machine.

WOW awesome!
Please share your SSS properties!
What level was reached?

Sweet render

that's really good looking. you could maybe add some actual candel flame in post, i think it would help loosing that geometric look they have right now.

The shader is very simple:
Color R:0.6 G:0.544 B:0.489
Spec L:0.4
Roughness U&V: 0.15
Absorbtion: 0.1
Scattering: 0.128
The render only got to 16.69, but there was a logarithmic falloff to the sampling level. The basic stuff like, level 10, was achieved pretty quickly but a progression from there onwards got slower and slower until, for example, 10 hours of render got me a change from 15.90 to 16.69. This was fairly typical from 13ish upwards. Hence my Ctrl-C and post; the World Community Grid wasn't getting any love this week...
If anyone has a supercomputer (or a more efficient new build, NL) and wants to finish it off, let me know.
Rivoli, I completely agree about the flames. I started out with polygonised maya fluids which looked great, but you know the rules about poly counts on emitters <sigh>. OTSO 2d work I always post raw here, as it's a render forum.

I will be more than glad to render your scene! Is it max7?
can you please e-mail me?

Excellent Jakegoat... a bit less noise, and maybe a bit more resolution and it could be a nice top breaking barrier in lighting complexity

i see, still i'd really like to see it with this last post touch. just for the sake of seeing a very good rendering
and some good compositing.

Great scene jakegoat!
Fantastic illumination there you have...
As a technical and artistic note, specularity should be lower than 0.4 here...
AFAIK, usual candles are not that much reflective, so I suggest you
something like 0.1 or better diffuse material for candles.
It will also reduce noise and speed up rendering.

Great idea, great light and great rendering! Please let it render some more when you find the time.

...superbe,...very nice man,..I like the Idea very much,..yeh,..if you find the time make it noisefree

Tom,
Good thought about the specular value. What is your number derived from? I agree about the candles' reflectivity and had done a few version where I played with UV roughness. I got a nice waxy finish by throwing an all white jpg into the Glossy Map parameter and dialing the strength. Unfortunately, I thought the image looked a little dull in comparison to the one I started rendering (which was posted here). Here's an example:
Olivier,
<shudder> 40 hours on a 1.5GHz. Admittedly I left the process low for much of it, but I don't use the machine for much except taping net radio so, you could say it was about 30 hours of focused rendering. Each emitter is a small elongated cube (so six faces) emitting 1 watt. Film speed is 50 ISO at f1, which is about what I would expect for this kind of lighting.
Oscar,
It looks like andronikos916 thought the file was Max, not Maya, so how's about this: I'm taking delivery of a dual 2.7 G5 later next week. I'll set this off with Tom's specular suggestions at a higher res and maybe it'll be useful for your marketing?
Finally, does anyone know the scalar of the emitter faces vs render times? If I double the complexity of the candles, will render time double?
Thanks for the kind comments, folks.
