There are two things I would like to address about these wings:

1. If these wings appear flat, I apologize, but it's become they are. Almost all wings in IMVU, at the time of writing this, are 2d. The ones that aren't meshers have spent a great amount of time with, and derivers cannot easily change the shape of them. More creative and easier to make wings mean 2d meshes.

2. The edges of the wings appear pixelated because I did not turn Blending on in the Previewer. The reason for this is that all wings have a glitch that shows when Blending is turned on, as you can see by the picture below. Thus, no Blending, so that you don't look super weird in rooms.

Why I avoid the wings glitch
