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!

For the past couple days I've been racking my head trying to create this complex acrylic material that resembles a piece of furniture i have. Basically its a pieces of thick refractive acrylic joined together its has a very nice glassy look to it, also, the back side of the vertical piece has a red colored less transparent strip of of acrylic instead of the clear. This lets the red color project and bounce around the whole piece from different angles, its a very cool effect. So i was able to get the bounce to work correctly but then i realized that the material i created wasn't behaving exactly like my sample. When i look at the sample i can see through the acrylic and see edges on the other side, it makes the depth and thickness and geometry of the object obvious even though its warped where faces overlap.Bellow I've attached a photo of the sample showing the location of the red strip outlined in green, and the effect im trying to achieve outlined in orange. My material isn't doing that and it looks frail and thin like brittle pieces of glass stuck together. I tried to sue a small outer shell modifier as a cheat to make get the effect i was looking for and it kind of worked but then i lost the red color bouncing around the objects. I could really use some help with this if anyone has mastered these kind of complex materials, I've always had trouble getting water to look realistic no matter how mater tutorials i watch its probably the same reason this is giving me trouble. I'm using Max2016 and vray 3.30.05 and my materials settings are posted below, thanks in advance for all of your help!!

Hello! I have a need for an Acrylic material and downloaded one. It is a VrayMat, a Clear Blue Acrylic. For the Life of me, I can't change the Blue to any other color! Herevis the .mat file: https://www.sendspace.com/file/xrjxom It is a simple clear blue material. The Diffuse entry is white and there are no maps? This is the strangest problem I have ever had... THANK YOU!
