I was trying to get an effect in a visor - a glow, like there's some kind of light behind a robotic mask.
I was obviously unsuccessful, but given we have the Spectrum effects (which I believe are painted on layers that glow) I wonder if it would be possible to give some costume parts a similar glow/luminescence effect.
I think it would definitely add to things such as eyeware, weapons, auras etc - but obviously I have no idea how achievable it would be. What I'd like to see is to be able to add a checkbox per colour with "add glow effect" etc.
It might be a wish too far but would certainly add to the costume creator
