I downloaded this and tested it out in game. But because it uses transparent textures, any cosmetic put on will cover it no matter if the eye textures are infront or behind the cosmetic. Its because of how $transparency works.

The way I had to make the cosmetic work was to cut out the picture from the flat mesh, remove the transparency and as a plus give it the ability to glow in the dark with $selfillum

Here is what my edit on it looks like with the illumination

I mean, other than that I like the idea. Goes pretty well with other things. My favorite being the deep sea diver hat

Mine are orange because my Special Eyes (what I put it over) were painted orange
