Glass reflection on double glazed windows

derek forreal · January 18th, 2008

hello all,

does anyone bother modelling double glazed windows? if so, do you use two planes or two boxes, or some other method?

whilst real glass in windows usually show slightly offset double reflection, most of the cg renders have pretty perfect reflections on glass and i don't think this is very accurate.

the only problem with modelling double glazing is that it makes the 'dark objects through glass' issue even worse.

thoughts?

Depends on the requirements of the model I'm building but I have modelled them properly in the past. Usually if they're seen at a distance then I don't bother as you can usually do it easier in post.
