Tint choices:
- Stock / Off - $0

Features:
- Universal support for compatible base-game and mod vehicles.
- Automatically bypasses vehicles that already include their own native tint configuration.
- Clear first-person interior visibility while keeping the selected exterior tint.
- Limo tint uses the approved glass-only rendering path with no cloned panes or opaque backing geometry.
- Windshield sticker and label handling prevents angle-dependent alpha sorting artifacts on supported vehicles.
- Exhaust remains fully enabled while the exhaust-side transparent sorting fix prevents smoke from revealing the cab through tinted glass, including at longer viewing distances.
- Multiplayer supported.
