Geoffc Posted November 7, 2009 Share Posted November 7, 2009 I'm working on an interior render, using a beach shot as the background map. I'm using standard vray fresnel glass. But as you can see, where the doors are open, the background looks correct, but the glass material causes the doors and windows to look fairly tinted. I've messed with quite a few settings (fresnel on/off), IOR, diffuse/reflection/refraction colors, etc, but I can't seem to shake the 'tint'. I must admit I'm no specialist with materials at all either. Suggestions? Thx! Link to comment Share on other sites More sharing options...
Stephen Thomas Posted November 7, 2009 Share Posted November 7, 2009 It would really help if you posted your material settings but the obvious answer is to up the value in the colour swatch for refraction. Also important would be the thickness of the glass and whether you're using any fog. Link to comment Share on other sites More sharing options...
Geoffc Posted November 7, 2009 Author Share Posted November 7, 2009 Here's the settings. The glass is 1/4" thick, but I just tried a plane object, no thickness, with the same material and got the same effect. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted November 7, 2009 Share Posted November 7, 2009 After seeing the settings I must say I'm a bit stumped. Link to comment Share on other sites More sharing options...
Geoffc Posted November 8, 2009 Author Share Posted November 8, 2009 So after trying everything, I inadvertently found the solution: vray cam exposure! I'm using a vray sun & cam, and photometrics on the interior. Iwas adjusting the cam exposure for something else, and noticed the glass get a lighter 'tint'. Doing other tests, this was not due to the interior lights or vraysun. So, I adjusted my vraycam exposure until the glass looked good, then adjusted my lighting to match. Looks good so far!

Stephen Thomas Posted November 10, 2009 Share Posted November 10, 2009 Great, glad you sorted it and lighting looks much better all round. Link to comment Share on other sites More sharing options...
DanGrover Posted November 10, 2009 Share Posted November 10, 2009 I agree, it looks much better all around! I am slightly confused by the light levels though - I can't tell what the weather is meant to be outside. It doesn't look too sunny, and if it were then then the windows would probably be bleached out quite a lot. But at the same time, the sky and sea looks quite blue.

Geoffc Posted November 10, 2009 Author Share Posted November 10, 2009 Dan, so far I've purposely 'cheated' the exterior light levels by lowering the sun intensity quite a bit. The render ends up looking much like either an HDR photo, or multiple photos stitched together. You are correct, a single shot on a sunny day from inside would really create blown out exterior exposures. Reason I did so, is this is being used by a realtor to sell a high end beach house, and prospective buyers would never recognize the irregularity, but will notice the beautiful outside environment.
