I’ve tried both the regular emission material node, as well as the Armory PBR node with the emission option turned up to the max setting, but neither gave any sort of glow effect to the object. Is there something I’m not aware of in my way or is this just not an implemented feature yet?
You need to add the bloom in the render settings to actually get the glow effect.
If you want to see the light shine on other objects, you can use the following node setup:
And, for good practice at the very least, set the blend mode from opaque to alpha blend. If you then stick a lamp in an object with this material, and set the lamp color, the object will appear to glow, casting light on other objects. However, I don’t expect it to work well with long and/or irregular objects.
