Picture worth a 1000 words and all that, so . . . Basically, some windows you can "see thru" fine, others it's like you can't see anything at all thru. Yes! I know some windows have "directionality" to them, but in some cases you can't turn the windows to a proper facing and in other cases the facing of the windows doesn't matter at all. Obviously you can completely bypass windows by going third person . . . but that seems dumb to me. Wouldn't it make more sense to make windows just not suck?
Heavy windows have two panes, so they're darker than regular window tints. Use the multitool on Change/Rotate mode and click the window to switch tints. As of 1.5, heavy windows turn almost completely transparent when their tint is turned off with the multitool. You have not done that here.
