6000.2.6f1 Release Notes

Improvements

  • GI: Changed the behavior of light probe loading. When you unload the last scene that contains light probes, you no longer need to call LightProbes.Tetrahedralize() to apply the changes. (UUM-116318)

  • VFX Graph: Allow the user to insert a template into an existing graph at a chosen initial position to avoid nodes from overlapping.

API Changes

  • Physics: Added: Physics::RebuildBroadphaseRegions has been unmarked from being deprecated due to multi-box pruning broad phase being brought back. (UUM-112553)

  • Test Framework: Added: IPostbuildCleanupWithTestData interface- same as IPostbuildCleanup but provides a TestData object.

  • Test Framework: Added: IPrebuildSetupWithTestData interface- same as IPrebuildSetup but provides a TestData object.

  • Test Framework: Added: PostbuildCleanupWithTestData attribute- same as PostbuildCleanup but provides a TestData object.

  • Test Framework: Added: PrebuildSetupWithTestData attribute- same as PrebuildSetup but provides a TestData object.

  • Test Framework: Added: TestData record- provides data about the current test run, including the test mode (editmode, playmode, player) the tests it will run, and the platform it will run on.

  • Test Framework: Added: TestMode enum- a mirror of the existing enum with the addition of 'None' and 'Player' to distinguish them as Test Modes.
