Emissive map with alpha

[mrbadguyva]

Hello!

I am trying to make a material in which parts are wood, and parts are a emitting (lit) glass. So i have for diffuse normal wood, then a generic bump, and a monochrome balck and white img, with white for the light parts.
But when I render, i don’t get the wood texture for the diffuse, having instead a black surface.
What should I do to make the emissive map transparent on the parts which sould not emit?

thank you…!

OK, figured it out…!

All I had to do, was to use a transparency map inside the emissive layer. This transparency map was exactly the same pic i used for the emissive map.
Cool.
