I would like to add the emission shader to the green parts of this texture. How would I do that? Edit: How do I make a mask from this texture

    $\begingroup$ You should create a mask texture that is all black except for the emitting parts which should be white $\endgroup$ – Duarte Farrajota Ramos Aug 6 '17 at 23:49

    $\begingroup$ Your going to want something lie this: imgur.com/a/8fcEJ I did this in photoshop, just select the colour range of green and then converted all of the green parts to white and put it over a black background. $\endgroup$ – masterj2001 Aug 7 '17 at 1:16

First of all you'll need a map that will define the areas where light is being emitted from, like this: Emission Map Then to mask it over the diffuse map you'll need to create a simple node setup where you use the new texture to control the way two shaders mix, the white areas will use one shader, the dark ones the other one:

Node Setup

(You don't have to use a diffuse node, I just used it for the example) Your final result should be something like this: Final Result Obviously yours will be on the actual model. Hope this helps.
