Emission on Shader

[ndumais]

Is there a technical reason why the shader is not emissive, or at least that the emission intensity is not currently modifiable?

Well, emission is basically just adding color to the rendered result, so that is arguably very similar to what the ...Additive shaders (which are included) are doing. So, maybe try those instead of the ...AlphaBlended shaders and see if you are able to create the desired result.

If not, then the way to go is probably to add a custom illumination shader by copying an existing shader and modifying its implementation by adding an illumination approach that fits your custom needs.

Ah, and the analogue to "emission intensity" would be to just change a color's Brightness via a color picker. But yeah, you can't select values > 1.0.
