Fixed regression in the ambient probe intensity for volumetric clouds. (#5546)

anisunity · web-flow · commit 3b223161ddb1 · 2021-09-10T10:57:10.000+02:00
* Fixed regression in the ambient probe intensity for volumetric clouds.

* Fix artifact non local low clouds

* Fixed the sun leaking from behind fully opaque clouds.
Changed the volumetric clouds presets.

* fix formatting

* Added an option for the ultra 1024x1024 mode for the volumetric cloud shadows and a filtering pass to reduce the aliasing artifacts of the clouds shadow.
Changed the number of steps to evaluate the shadow from 9 to 16.

* Additinal fixes

* Added a new sun light dimmer on the volumetric clouds volume (case 1364152).

* Fix error cloud ambient probe

* Update all the clouds screenshots

* review fixes

 - Fixed edge bleeding when rendering volumetric clouds.
 - Fixed the performance of the volumetric clouds in non-local mode when large occluders are on screen.
 - Fixed a regression that broke punctual and directional raytraced shadows temporal denoiser (case 1360132).
+- Fixed regression in the ambient probe intensity for volumetric clouds.
+- Fixed the sun leaking from behind fully opaque clouds.
+- Fixed artifacts in volumetric cloud shadows.
+- Fixed the missing parameter to control the sun light dimmer (case 1364152).
+- Fixed regression in the clouds presets.
 
 ### Changed
 - Visual Environment ambient mode is now Dynamic by default.
