Just a simple VFX Editor mod I did because I have an RGB addiction, and I'm just now learning how to utilize VFXEdit, on top of material edits for a glassy look for the bow! (There's an option for default, no worries)
Be warned, I've had issues in the past with the glass shader causing crashes as I might not have set it up right, and even crashed when I did on some items, thus far I've had no issues with the bow however!
P.S. Penumbra .pmp installer only as it's all I use for modding in most cases!
