VRay Glass Tile Material?

[rmccoy]

I am stumped on how to make this material. I am needing to make a glass tile with grout material. This usually is very easy. However, I need the back side of the tile to be a painted white and the rest of it to be a regular glass. It also needs to have some thickness (.25") to it. The grout needs to be a slight off white color.

 

I am trying to keep from having modeling all of the tiles and doing a multi/sub material.

 

Thanks in advance for any suggestions.

Is there a particular reason you don't want to model it? I think that would be your best option

I would think a multi sub material would be the easiest and render the quickest.

Or have your glass blocks mapped with your glass material and use an opacity map for the grouting. Then put a plane behind it for the painted side.

Thank you for your responses. I ended up modeling the tiles and grout and placing a second white painted layer behind the tiles. I was trying to keep from doing this because my boss was still unsure of the exact material choices for the bathroom and would change his mind most likely. Thanks again!

Multi-sub works in this situation.

 

Model a box, convert to poly

Select back side face, reverse the face, set it to ID 2, select inverse, ID 1

Apply multi-sub mat, paint for ID 2 and your glass tiles shader for ID 1, should work.

Thanks for the suggestion.
