better vraymaterial shader

[saudade]

Vraymaterial is enough for us...but....
I think that the refractions are not managed well inside vray. For example Hypershot glass material has a lot of parameters more...and if you see how it renders glasses you will say WOW!..they are realistic...the same is for the metals...or carpaint shaders.
For example I modeled a scene with a water glass then I filled it with a 3d liquid.
Normally glass has an ior of 1.5 but if I look the glass in a front view I see the liquid inside too much refracted. In reality this not happens.
The trick is to lower the IOR, but the water glass parts that have a big thickness are no more realistic.
I attached here 3 shots renderd with vray 1.5sp3, they are simple tests done with pflow and glue. the glass has an 1.2 ior

Cheers!

I disagree. I've used Hypershot and found it too unrealistic, but to each his own in that regard.

I think your materials are perhaps a bit off in Vray though. I have had no real problems getting good liquids in Vray and the way it handles dielectrics was one of the key reasons I switched to using it 1.5 years ago.

Here's a render done for part of a recent job - I thought it looked pretty good and the refractions were quite good. Tons of area lights, lots of mo-blur and Vray handled it no problem.

Main liquid was done in Realflow and the small blobby sprays were done using the Pwrapper from Glu and a Superspray particle system.

beautiful image....
I don't want to say that refractions are bad in vray but lacks some parameters to tweak the refractions...for example ior in and ior out like used in the hypershot shader.
Talking about your image I'm playing with Glu but I can't generate motionblur with vray, the only way is to add mblur with Refx plugin inside After Effects, but for a static image is impossible...
Any suggestion?

I may be wrong, but I think IOR in/out settings on a material are physically incorrect, so less realistic. I think they are necessary for render engines that do not handle the stacking of IOR's the way Vray does - so they are actually not needed in Vray if you interpenetrate your liquid and glass etc. Vlado can correct that if I am wrong.

AFAIK you cannot do motion blur with Glu meshes so you are probably on the only available track unless you want to go to something like Realflow, or look at Bercon's Metaball plugin. I have not had time to play much with that but it can do mo-blur if you can get it to work with Glu particles.

vray mat is a very much physically accurate material, however it has a lot of extra options to allow user to add extra, since often physically accurate may not be the best desired result.
What I would, and have been asking for is a separate material set. Something that has a refractive/reflective pats separated.
For example a pure glass shader, or plastic etc.
