2022.1.21f1 Release Notes


  • 2D: [com.unity.2d.pixelperfect] Added URP Pixel Perfect Camera converter.

API Changes

  • Shaders: Added: Added an API to control shader memory usage at runtime. (UUM-5583)


  • Universal RP: Messages regarding reducing resolution for additional punctual lights are now only displayed in debug builds. (UUM-10166)

  • XR: The Oculus XR Plugin package has been updated to 3.2.1 with support for Quest Pro.


  • 2D: Fix memory leak with the TilemapCollider2D when used with a CompositeCollider2D (UUM-15822)

  • 2D: [com.unity.2d.animation] Fixed a case where moving vertices forcefully in the Skinning editor could cause a quad reset of the mesh. (DANB-7)

  • 2D: [com.unity.2d.animation] Fixed a case where multi selecting Sprite Skins would cause a null reference exception to be thrown. (DANB-126)

  • 2D: [com.unity.2d.animation] Fixed a case where pasting bones in the Skinning Editor would move bones rather than copy them.

  • 2D: [com.unity.2d.animation] Fixed a case where setting IKManager2D's or Solver2D's weight to '0' doesn't update solver's effector position.

  • 2D: [com.unity.2d.animation] Fixed an issue where selecting bones in the Skinning Editor after removing any bone in the skeleton will throw an exception.
