Hello!
First off, I did look around to see if this was mentioned anywhere and I didn't find anything relating to this so if there is something and I missed it, I sincerely apologise.
Anyways! I'm not sure if this is an intentional thing but the glasses 'g_squares' and 'g_squares_tinted' use the exact same texture. Judging from how they're named, my guess is that 'g_squares' is meant to be square glasses that are transparent (y'know, like proper glasses) and 'g_tinted' is meant to be a sort of sunglasses version of it. Maybe I'm wrong? I'd love to hear some feedback about it!
Regular
Tinted
Hope to hear from you soon!
All the best,
L
