Here is a quick test I did.

Using a directional light and an HDR, 3 materials, one for the window, one for the bottles and one for the rest of the set. The bottle material is using fresnel and absorption. Setup time was about 5 minutes, rendertime about an hour with DOF, GI, and 13 reflections/13 refractions.

modo 201



I'll play with it some more and see where else I can push this scene. Thanks for the geometry to test with.

Thanks for the comments herbertagudera. The shaders are just some procedurals I threw together in Cinema4d except for the pink one which is one someone posted in one of the cinema forums. To be honest I don't remember who it was.

Same setup, added a few textures and rotated the HDR image. I also lowered the absorption distance.

16 minute render, got rid of the directional light, changed which HDR I'm using, and varied the color/absorption of the bottles...

I don't want to play with caustics no more! so i fake them..
I'm happy at this point with glass and "caustics" -
i need to give some changes with color and fuel..
Then i can work on the set - this may be a room, and you can see outside in the dark..
and there's a lamplight in the room (for me the outside is the part with no floor) =
cold light from the outside (blue) and warm from the lamp (yellow).
the environment could be any hdri so the bottles can reflect in a more realistic way, but i haven't figured out yet what one can see thru the window.. Help!

(i may change my mind becouse i can't find anywhere a ledge inside the room) hmm..

Elvis75K,

Seriously, caustics take near forever (barring a few tricks that I need to adopt) for just a few "sparkles" in the render. They look really cool, but at a seriously expensive cost. I like what you are doing by faking the cautics. I definitely like where you're going with this. mental Ray kicks ass (if that's what you are using), but it seems slower with some things, especially motion blur...

i like this more and the one shader solution is also a good test (the green bottles)...
The absorbtion is very nice.

hi all im finaly gona upload som WIP´s hope u like em, trying to get that sea feeling! of an quite old house near the harbour...

this is a verry compressed pic and with added noise in "ps"

Ok here's an update. I want to increase my transparency in all bottles and try out hdr lighting cause I've used a skylight and a MR omni and it takes half an hour to render with gi 500 and fg 100 (max's mental ray). I put a blue color as environment. C&C always welcome

lots of good images here. Here is my attempt so far:



It's really eary and spent only about 10 or so minutes on it. But was trying to get a certain look before I went on to materials.....that'll be a challenge for sure! Hopefully I'll be able to finish this one unlike the four scripts challenge. It's rendered with mental ray (gonna use it for the glass) with one raytraced light and the rest shadowmap.

update from Slatr

Hamburger, I tried to comp a sharper background image.. not a whole lot of high res pics of kilimanjaro but let me know what you think

EDIT: and here is one with the glassworks shader from Nitisara

Still very much a WIP. I don't know what's causing the black squares, but it might be a bug of some sort. I'll see if I can get rid of them. No textures yet, and the glass shading is fairly primitive (I can't get absorbation to work properly in Kray). I'll post an update sooner or later, with textures and hopefully no black squares, and possibly more variation to the glass.

Your scene is coming along well. I think I recognize the problem with the refraction there: it appears to be missing the "exit" refraction in the back-faces. If you have a glass-like IOR (like 1.4-ish) but the orangina bottle on the right is turning into such a powerful magnifying glass as if the whole thing were a solid lens, then the problem is probably that the surface is refracting as if it is single sided, and not doing the refraction back out into air at the first inner wall of the bottle.
