![]() So give it a nice HDR background and lighting or a nice scene to sit in and voila, Vray glass. But don't forget that refraction and reflections need something to refract and reflect. You usually don't need to use very saturated values of the colour in the refraction. Now the colour of the refraction will control the colour of the glass. ![]() That's good in this case, but if you wanted to do say a glass window (where there is no refraction) then you would set the IOR to 1. BUT because the default IOR is 1.6 that means that it will refract the background. Black is opaque, white is 100 Transparent. Then we go on to refraction which is what controls transparency in Vray. If you made it 100% red, then the reflections would be tinted red etc. ![]() Im not 100% sure if glass adjusts the colour of the reflection (I don't think it does) so we make the reflection colour any value from black to white. than at the front (same with plastic, but NOT metals). Glass reflects more at the sides of bottles and glass etc. Then turn fresnel reflection ON for the glass. ![]() make diffuse the colour that you want the glass to be. ![]()
