Glow only ?

Is it possible to setup a material that’s glow only ?

brief explanation at 7:29 and later in this 5 part series he explains emissive in more detail. This guy, at least to me, is giving a really good rundown of the engine details. Anyway, Good luck!

Had a look and not found anything I’m missing. If I create an object and give the material emissive only the color gets intense and starts to glow but no glow without the object’s color. Best to describe this, as if it were a light volume so only glow.

You need to use a GI solution or bake static lighting for that to happen.
