colored frosted glass

[Neelu]

Hi
How could I make a material for colored frosted glass?
This is what I have made for regular frosted glass.

Use this (shown below) to pick the colour you want, and then play with the fog multiplier to get the intensity to suits your needs. A fog multiplier of 1.0 is too high, so I suggest starting with .05 or .07 and range it to around .5 or .6, to get decent colouration. You might also have to increase the frosting (reduce the glossiness value) to accentuate the internal refraction and intensify the colouration.

I also suggest doing test renders with a few panes of glass in a simple setup ( lower your subd. values as well) to see how they each look against either a plain glass or a non-coloured frosted glass to get what suits you best. It's tricky but as with anything else in rendering, you have to go through a lot of trial and error to get what you want.

Hope this helps.....

I think it's done with the fog color. Check this tutorial:

Doh! Simultaneous (almost) post.

Thanks!
This is what I got with new color settings.

Can you post your settings for your final result please...

Thats the thing I hate about frosted glass is the render time. 17 minutes seems long to me especially if you have a great deal of frosted glass objects in a scene among other reflective objects. Is this normal?

Definitly normal
Just cause it's physicaly and mathematicaly more difficult to calculate.
Reflect/refract are the hardest thing to render, so if u blur it (reflection/refraction glossiness), that will be more and more difficult.
You can tweak reducing the maxdepth and the subdivs instdead of quality.

U can try that for your reflective/refractive materials :

reflect/refract glossiness : 1
maxdepth : 5
subdivs : 8

reflect/refract glossiness : 0,8
maxdepth : 3
subdivs : 12

reflect/refract glossiness : 0,6
maxdepth : 3
subdivs : 20

hi all,
Here are the settings. Try it out. Strangely, as I lowered the refraction glossiness to 0.6, render times were shorter and as I increased it to 0.85 render times were longer.

Nothing strange about that; as you lower the glossiness and the blurrier or stronger the frost effect gets, the less definition that V-ray has to calculate for the objects behind the glass. And vice versa with the reverse; as you increase the value, the 'clearer' the object becomes and the more definition or resolution that has to be calculated while still factoring in the glossy refractive or subsurface scattering effect.

Thank you for sharing the setting, but how could i save it for use in future ?
do i have to remember the numberic and set it everytime when i want to use it ?
