If [code]true[/code], enables new physical light attenuation for [OmniLight]s and [SpotLight]s. This results in more realistic lighting appearance with a very small performance cost. When physical light attenuation is enabled, lights will appear to be darker as a result of the new attenuation formula. This can be compensated by adjusting the lights' energy or attenuation values.
Changes to this setting will only be applied upon restarting the application.

Size for cubemap into which the shadow is rendered before being copied into the shadow atlas. A higher number can result in higher resolution shadows when used with a higher [member rendering/quality/shadow_atlas/size]. Setting higher than a quarter of the [member rendering/quality/shadow_atlas/size] will not result in a perceptible increase in visual quality.
