My first VRCMods upload. The glasses can fold and open, just make sure you select the bone in the hierarchy and change the rotation mode to "Pivot", and "Local". Change the materials and shaders however you please. If you're a beginner and want to just put it on your head, I suggest leaving it out of the hierarchy, posing and sizing it exactly how you want to look, then drag it under the head hierarchy. If you're using dynamic bones, make sure you put them under "Exclusions". I sculpted this all on my own, please enjoy!
