UE4: Adding Emissive Light to a Part of a Texture

1) Create a copy of the original texture and highlight only the parts that should shine in either red, blue, or green
2) Multiply that texture sample with a vector parameter representing the light color (using the appropriate red, blue, or green channel from the texture to isolate the area to light up)
3) Multiply this by a scalar parameter called emissive strength so that you can pump up this value to make the shine brighter
4) Wire this into the emissive color channel
