Material which looks like a facade of a building

Hey there.

I have a bitmap of a facade of a skyscraper. I want to map it onto the surface. but it looks quite dark. How can i make the material self illuminated to get the feeling of liten offices ?

thanks

You can use the new vray light material (1.45.70), or you can use a standard material, with a self illumination map, wrapped in a vrayMTLWrapper.
