2021.3.32f1 Release Notes


  • HDRP: Added a warning to the HDRP Wizard if a users project contains materials that cant be upgraded. (UUM-46394)

  • HDRP: Improved skyContext caching when the sky renderer changes. (UUM-43697)

  • Kernel: Added "-timestamps" command line argument to the player, which makes it prepend timestamps at the beginning of each log line. This setting was previously only available to the editor.

  • Universal Windows Platform: Improved performance of repeated checks whether accelerometer and gyrometer are supported.

The minimum screen brightness value will be capped at 0.04, since setting this value lower would default to system brightness setting. (UUM-47926)
