Need help with Vray

[ip14]

Hi this is my first time using Vray and i'm chased by deadline for my final assignment . I encountered many problem with vray for sketchup (i'm using version 7.0) and any help would be appreciated. Here's my question :

1. I already paint a glass with default translucent material from sketchup (both face, front and backward) and make sure there is no plane behind the glass, but why each time after i render, the glass look solid and not transparent at all. Any idea?
2. My building color is almost all white, i want to ask how to make the final rendering have a little noise in it?
3. Where i can download good VISOPT option for exterior rendering?

Thank you very much!

1 go to the asgvis forum and search the really good glass tutorial by nomeradona. It really helps to learn how to make a glass material

2 use a perlin noise bump map?

Single sided or "thick glass"?

For single sided:

• make the material fully transparent (If you want a colour to it, you could put it somewhere between 0-5% transparent)
• Add a reflection layer to the material - with Fresnel map.
• Adjust the Refraction value so it's not completely black, value 30
