Rebased and finished version of https://github.com/bevyengine/bevy/pull/8407. Huge thanks to @GitGhillie for adjusting all the examples, and the many other people who helped write this PR (@superdump , @coreh , among others) :) Fixes https://github.com/bevyengine/bevy/issues/8369 --- ## Changelog - Added a `brightness` control to `Skybox`. - Added an `intensity` control to `EnvironmentMapLight`. - Added `ExposureSettings` and `PhysicalCameraParameters` for controlling exposure of 3D cameras. - Removed the baked-in `DirectionalLight` exposure Bevy previously hardcoded internally. ## Migration Guide - If using a `Skybox` or `EnvironmentMapLight`, use the new `brightness` and `intensity` controls to adjust their strength. - All 3D scene will now have different apparent brightnesses due to Bevy implementing proper exposure controls. You will have to adjust the intensity of your lights and/or your camera exposure via the new `ExposureSettings` component to compensate. --------- Co-authored-by: Robert Swain <robert.swain@gmail.com> Co-authored-by: GitGhillie <jillisnoordhoek@gmail.com> Co-authored-by: Marco Buono <thecoreh@gmail.com> Co-authored-by: vero <email@atlasdostal.com> Co-authored-by: atlas dostal <rodol@rivalrebels.com>
