transparency mapping

Hello All,

I recently updated to Vray 3 for Rhino and I cannot figure out how to add transparency to my decals. There used to be a ‘transparency’ option along with diffuse and I used to do it by clicking the ‘m’ button and selecting my black and white version of my decal, however now I cannot find any such feature on Vray3. There has to be a way to create decals without the white background but I am stumped! This link shows how to do it for Vray 2, but I cannot find anything for Vray 3. Can you help me?

Thats it! Thank you Ben
