maxgooday Posted January 15, 2013 Share Posted January 15, 2013 For some reason and I'm not sure why but I've got a camera in a scene which is looking through 5 panes of glass (so 10 sides of glass) and the glass is rendering out very milky in colour. I have tried playing around with the settings of the material without any joy. Can anyone please help me on why the glass is looking so washed out. It needs to look more reflective and richer as you view through all the glass. See test render and material settings below; Link to comment Share on other sites More sharing options...
Ismael Posted January 15, 2013 Share Posted January 15, 2013 With such bright light outside there should be almost to no reflections from the inside showing on the glass. Just like reflections get 'eliminated' here: http://www.adorama.com/alc/0013787/article/Lighting-for-High-Key-Glass-Part-II With the camera outside lokking into the building, the outdoors would reflect on glass. Brighter wins. Link to comment Share on other sites More sharing options...
Corey Beaulieu Posted January 15, 2013 Share Posted January 15, 2013 Try upping your max depth value to 10. Also reduce the IOR to 1.6 and maybe check out the environment override for refraction (turn it on, but leave it black). I would try one at a time and then check out all three.

Francisco Penaloza Posted January 15, 2013 Share Posted January 15, 2013 While Ismael is right pointing that lighting play a main role here, it is important also that, if you have any tint in your glass this one will increase every time that you cross a new glass panel, making the final image tinted, blurry or distort depending of your glass properties. Now the default max depth for reflection and refraction is 5 this cover most of the cases, when you have a special situation like yours when the camera and light need to cross several glass panels you need to increase this value, a single glass panel has 2 bounces, 2 panels 4 bounces and so on, in you case the minimum should be 10+ 1 or 2 to get environment reflections, be aware that your rendering time will increase accordingly.
