VRay's nightmare...!

What IOR should the bubble material have? Something like 0,667 (the inverse of water's 1,333 if you take 1 as point zero) ?

Thanks 'n' cheers!

Beautiful!!!

Yes, when taking 1.0 as the reference point it would be 0,667.

Thanks very much for your flattering comments guys, I really appreciate it.

Bubbles added, with an IOR of 0,667 (this page might need a reload to reveal the new image version). Works fine I think. Thanks to Spirit for convincing me to add the bubbles after all and to Stefan for the scientific theory.

Cheers!

Hi Metin. Very nice image! As for the indexes, the transition material from glass to water should be IORglas divided by IORwater. See also my post in "Liquid in glass test - in reference to Metin_7's post"-thread.
I am not sure though how max/vray handles rays that go through the new surface. I am used to render inside Rhino (with Flamingo) This software automatically breaks the ray back when it meets the second surface, even when it is another object/material. If max doesn't do that, you will need to use IORwater divided by IORglass. (sorry, don't have vray yet and beta is expired )

Thanks Gijs, I'll keep your tip in mind for my next liquid in glass project.

Cheers,

Great job

Great job, it looks wonderful!

Just wondering, exactly how long did it take to render that frame?

[Metin_7]

Thanks!

Rendering took an estimated 10 hours. Resolution: 1280 x 1280. AA settings: 0, 2 and a lot of VRay's talents used (caustics, blurry reflections, refractions, HDRI environment lighting, VRay lights, GI with irradiance map and direct computation). GI sampling: -2, -1.

Cheers,
