ice material...

Were you scattering objects on a surface for this or is it a volume / continuous surface? Looks great!

Bit of both: it's a noised-up surface but then some displacement and on top of that I scattered some crystals with Forest Pack Pro

Looks pretty good! How far did you push the refraction glossiness? I think you can get that depth in the ice with more glossy refractions. It will help the translucency too IMO.

Caustics would be good, but I'm not having much luck getting good caustics on such small refined shapes.

sorry to get back so late, but was rendering and couldn't enter settings.
here's how mat looks like

also a bit of bump

Brett awesome results. I tried your way with forest and crystals but I had to render 3000x40000 res and just one bucket when on ice part was taking 10 minutes to render !!! So I passed

Your mat looks good. I think .99 glossiness isn't enough to give you that translucent look though. I used a much lower glossy value and it does much of the translucent effect, but renders fast IMO. FPP/scattering to do *all* the crystals was super slow - I gave up too. I just used it to add 500-600 crystals on top of the displacement/bump effect and it adds that nice bit of detail but wasn't too bad to render at all.

yeah at first few draft that I showed the client I used aroudn the value you have for refraction glossiness and got the comment form client that it looks like gel not ice
so you know ... we got to keep client happy

I hear you Yours looks very good, no question - I think I mostly avoid SSS type stuff because I love using VrayRT for lighting and material development and tend to not use stuff that still doesn't work with it. Hopefully that will be added soon....

Anyway, I'll try your setup out. Thanks for sharing it.

Brett, awesome results. Wow. I'm going to play with this when I get home. I'll see how well I can do, which won't be as good as you both .
