Hi I’m trying to get a flame and smoke sequence from Ember gen mapped onto a polygon card.
I rendered out the flame and smoke as separate as PNG files.
I need to be able to boost the emission of the flames so they are brighter and less muddy.
Note I am not using VDB files. While they work after you clone them a few times they bog the scene down.
I have transparency on in render settings, the alpha channel of the polygon is set to Alpha blend.
I’ve tried both eevee and cycles
What I’m trying to figure out is how to apply an emission shader to the flame and still use the alpha channel.
You need to mix an transparency shader with an emission shader. The alpha goes into the factor of the mix shader. That should be it, if I understood you correctly.

Like @Romanji said…just use a mix shader with an emissive and driven by the alpha factor…here is one I have used…
NOTE: I almost always use a transparent node with anything like this to stop the effects of the principled from affecting the image plane…( also works well when there is not an alpha channel as in this case…use the color of the anim background to factor the transparency)
