Getting image texture to affect emission value (cycles).

Support Materials and Textures

I want to get an image texture to affect the value of the emission strength of a material.

So far I’ve been able to get a procedural texture to do that by plugging the texture’s output to the strength input of the emission shader node.

But for some reason the same doesn’t work with image textures, all I get is complete black, zero emission.
So how can I get this to work?

I have to have a look at this myself shortly for a project I’m working on, I wonder if you need to use an alpha png perhaps?

it seems to be easy as it seems :wink:
maybe you had to set the texture coordinates

Oh yes, that’s what I missed. Thanks a lot lsscpp.
