Real Windows for Kerbal Space Program 1.12

Features

• Interiors shown through windows. In flight, the windows of every crewed part show its interior (IVA) from outside.
• No configuration, any part. Windows are found automatically from each part's own textures and interior, so stock and modded parts work out of the box.
• Glass windows. Reflections at grazing angles, a sun glint and faint smudges to simulate a glass layer.
• All vessels in view. All vessels within range show their interiors, even when not the active vessel.
• Open hatches look through. With FreeIva installed, an open hatch shows the next part's interior through the hatch.
• Optimized. Interiors are rendered only where a window is actually on screen, only over that area, and the static cabin is cached between camera moves; crew still animate every frame. Alt+F8 switches the mod off and on in flight. Expect around 10-15% less FPS with the mod active. (The stock "Show Interiors" option is about twice as expensive!)
• Configurable. The look of the glass and the render quality and features can be changed in the settings to trade visual quality for performance. At half interior render scale, there is barely any performance impact.

Requires KSP 1.12.x.

Optional: FreeIva.

Shaders are included for Windows, macOS and Linux; only Windows has been tested in game so far.
