I want to apply a transparent texture to an emssion node in a way that the the emission node will emit just from the not transparent parts of the image texture. How to achieve this effect ?

Here' s a Picture of it enter image description here

    $\begingroup$ Use the alpha as the factor for a mix shader of Transparent and Emision $\endgroup$ Sep 15, 2014 at 11:21

Are you going for something like this?

Glow with transparency

If so, then it's as simple as someonewithpc said, just an Emission shader mixed with a Transparent shader using the texture for the Fac.

  • $\begingroup$ hey, i am using this setup but I want to animate the map. Not simply control the total transparency of the texture but rather for example have a spherical alpha ring / wave effect on the texture. Would anybody know how to do that? Technically masking the texture that goes into the factor node for the mix? $\endgroup$
