I am trying to set up a winery scene with a plexiglass grid as shown in the picture below.
My vray mtl is working as expected, except for the glowing side faces.
I think (correct me if i'm wrong) that the effect i want to achieve has to do with
(fog color-mult-bias, and or refraction exit color and or dispersion).
For simplicity and speed reasons i'm using
Refraction color: white
Amount: 1
Gloss: 1 (will lower it to 0.94-0.98)
Ior: 1.49
I did some research online and most threads about this matter are rather old and most recommend faking the effect using self illumination etc. I also read that in reality this effect is happening due to sanded and roughened sides of the material.
The question is, how should i approach this kind of situation in terms of light/shader interaction and rendering speed? One vrayMtl and experiment with fog and or exit color? Different shader to the glowing faces ? Or some king of coated material and uv mapped different values to the side faces?
Any help or suggestions will be very appreciated!
