Single decals on windows

[Snix]

I would technically even work because of RenderWare GTA engine and it's transparency rendering.

I'm not sure tho, logic is it WOULD and SHOULD work but idk if a vinyl with alpha background going over a 100% transparent material (paint on a copy of the window) will show up as normal, like on the body or if it would just glitch out (double poly, Z glitch), some testing and playing around needs to be done to confirm it
