- Resave all files with Godot 4.4 to make use of script/shader UIDs. - Use AgX tonemapping in all demos that used a tonemapper other than Linear.
Physical Light and Camera Units
This demo showcases a physical light and camera units setup. This allows you to use real world units for lights (lumen, lux, Kelvin) and cameras (shutter speed, aperture, ISO sensitivity).
By default, Godot uses arbitrary units for many physical properties that apply to light like color, energy, camera field of view, and exposure. These properties use arbitrary units, because using accurate physical units comes with a few tradeoffs that aren't worth it for many games. As Godot favors ease of use out of the box, physical light units are disabled by default.
If you aim for photorealism in your project, using real world units as a basis can help make things easier to adjust. References for real world materials, lights and scene brightness are wildly available on websites such as Physically Based.
