Eyes drawn for a commission! I was given permission to upload it publicly. Now before I get corrected, yes I am aware that a waxing crescent isn't positioned that way. Unfortunately, if I were to make it an actual waxing crescent, it would look a bit funky. So the name stuck because that's what the idea was initially.
To have the glow/emissive, you have to go into advanced editing, materials, and look for the material that's being used. If you have Asymmetrical Eyes Framework by Midori, you can have a second glow option under IRI_B material instead of just IRI_A.
