Just trying to find the most efficient way to render refractive windows in a situation when angular refraction won't be noticeable.Is there an equivalent to Corona's 'simple' refractions in Vray? (not sure if this feature still exists in Corona, I've not used it in a while). If I set refraction IOR to 1.0, would that be the same?
Also is it still true that a refractive material applied to an open geometry will be treated as infinite depth?
Thinking about it further, I've been usiing the OSL windowbox texture to good effect for low-res interiors, if this is going in the diffuse slot, I can probably do away with the refraction completely and have the glass reflection and the simulated refraction on the same material..... I was putting it on it's own plane previously, behind a plane of glass. Would still be good to know the answer to the above though.
