Decomposing the refraction element

[jstrob]

Hi,

I would like to know if there would be a way to decompose the refraction element in multiple sub-elements.

I have a watch with a glass over the dial and when I render it in elements, everything seen through the glass become part of the refraction pass (reflection diffuse, etc all baked together)... But I would like to have control over the things seen through the glass and still get the deformation from the refraction...

Asked for it ages ago.... so we might just grab a beer and w8 for it :P

I am trying something: I will render the glass on a separate layer just to extract its reflection and normal pass. I will then render another layer with the watch and the glass not visible to camera and no shadow casting. I will try in comp to reproduce the refraction with the normal pass... we'll see. I'm rendering right now!

Finally it's very difficult to get good result in comp for refraction.

Let's just hop chaosgroup find time to add elements such as vray_ReflectionThroughRefraction; vray_diffusefilterThoughRefraction, etc...

I'd really like to see this too.
