Title: Can´t make Green Glass ?! Always Redish
Post by: kumodot on 2013-03-29, 23:34:52

Hi..

   I don´t know if it´s a bug. I am using a Multi-Sub Material and had to put 3 Glass pieces with RGB colors (RED Glass, Green Glass, Blue Glass).
    After making the Red Glass, i can´t make green Glass. It´s being Pink and Redish ... Very Strange.

remove the diffuse color (set it black).
Next, either make both reflection+refraction green, or try making them both white and setting absorption to green and tweaking the absorption distance

   Removing the Color from Difuse solves it, but is it correct ?
   
     Now i can see a litte bit of red on the specular ... It stills strangelly tenting to tint specular with red...

yes, it is, since glass contains no diffuse part. Normally it gets tuned down automatically, but not in this case, since you are using colored refraction.

     Sorry to keep pushing this key, but did you look my last screenshot ? I´ve follow your instructions and now the specular looks a little bit red.
     
     Anything wrong with my shader ?
 
      Tks keymaster ! :)

Remove the color from absorption and let it white of you decide to use refractionreflection color ;)

OR ( you didn't see it i think )

Leave the blue color in absorption and let the white reflection/refraction on white.

I tried the color only on absortion and the glass came out "white".

     I will try to leave absortion just white. Tks!

     I will do more tests with abortion :)

Change it to onesided (solid) and increase the absorption value with a high value ( the more value you add the more the color is reduced )

Second option with reflection/refraction color only
 and that works with onesided(solid)

No, i will not do more tests with ABORTION.

    I will test absorption. lol
