2021.3.14f1 Release Notes


  • Animation: Further improvements to animation job performance (esp. some forms of IK).

  • Asset Import: Improved performance of asset imports in large projects.

  • Editor: Reduced the time taken by AssetDatabase.FindAssets when used with a custom filter, speeding up domain reloads and other editor operations that made the poor choice of calling this function in the first place.
