Dynamic Lighting from Emissive Materials
Is it possible to do this in UE4.11? Don't think adding Dynamic Lights to each Emissive Projectile is gonna be performance friendly.
The discussions I've come across are all for older versions involving a "hackish" method with ConsoleVariables.ini, so I'm wondering if I've been missing out on anything, since there hasn't been any mention of this by other users for UE4.11.

That link uses the experimental Light Propagation Volume which has not seen a lot of love and i would not rely on it for your tech too much.
If we are talking a small amount of projectiles then having attached lights may not be too bad, just keep the attenuation low, turn off all shadows, and clean them up properly afterward. This would be quite simple to test so maybe try it out and see what's what.
Alternatively you could do some shader tricks like attach a sphere around your projectile with a material that volumetricly-ish brightens the scene behind it. Would only affect things seen through it but could give a feel of light around it.
I have used quite a number of lights in a similar situation and come out fine. Just optimize them.
