6000.5.8f1 Release Notes

Fixes

  • Adaptive Performance: Fixed Visual Scripting nodes (bottleneck, thermal, performance level, boost, performance mode, and scaler events) no longer firing in the player after Adaptive Performance moved into the engine module. The events are now forwarded to the Visual Scripting EventBus from the adaptive performance samples package assembly, where the VISUAL_SCRIPTING_ENABLED define is active. (UUM-135587)

  • Adaptive Performance: Gate Adaptive Performance settings during package operations. (UUM-140197)

  • Animation: Added a default HelpURL link for the temporary InvalidStateMachineBehaviour script. (UUM-143986)

  • Asset Pipeline: Fixed an Editor crash in WriteObjectToVector / CreateOrReloadInspectorCopy that could occur when entering Play Mode. (UUM-112617)

  • Audio: Fixed assertion about access version needing be odd when acquiring locks in an audio subsystem, happening after the editor was left running for many days. (UUM-146734)

  • Editor: Added a static function CleanupRenderPipelineIfActive to prevent activeRenderPipelineDisposed from firing while disposing non-active render pipelines. (UUM-148022)

  • Editor: Codesigned several previously unsigned executables shipped with the Windows editor that could sometimes be blocked by antivirus software. (UUM-147382)

  • Editor: Disabled advanced font features for UITK editor text. (UUM-147689)

  • Editor: Disabled Remove buttons in Build Profile settings during Play mode. (UUM-143194)

  • Editor: Fixed a bug where clicking "Revert" in the prompt that appears when a build profile loses focus after adding a scripting define value in the scripting defines settings list does NOT result in removing the newly added value. (UUM-147113)

  • Editor: Fixed a crash in the Editor shutdown path where an asset import worker process force-killed during teardown could corrupt the heap in WorkerManagerASIO::~WorkerManagerASIO, causing the Editor to abort. (UUM-135237)

  • Editor: Fixed a LegacyRuntime memory leak. (UUM-145108)

  • Editor: Fixed Adaptive Performance Settings removal with Android Provider causing errors. (UUM-143194)

  • Editor: Fixed an issue where disabling the mimalloc memory allocator for the Windows standalone player did not work. (UUM-147576)

  • Editor: Fixed reverting all presets not reverting the Main Toolbar to Unity Default. (UUM-142163)

  • Editor: Fixed the "Remove Component" menu missing from components with a missing script in the Inspector. (UUM-146874)

  • Editor: Updated Stats window to use M suffix for triangle and vertex counts 1 million or greater. (UUM-146878)

  • GI: Fixed a bug where "Refresh Virtual Offset Debug" throws an exception if the last bake didn't have Virtual Offset enabled. (UUM-147479)

  • GI: Fixed the custom environment reflection cubemap being forgotten when changing Source in the Lighting window. (UUM-133122)

  • Graphics: Fixed incorrect mipmap level calculations when using XR with "Minimize Unity 'Screen' Size" optimization.
    The camera rect in XR now correctly returns single-eye dimensions instead of combined stereo dimensions on SRP. This affects any system that relies on camera rect for resolution-dependent calculations, including mipmap streaming and resolution-dependent UI/text rendering. Adjust mipmap streaming settings or UI scaling if needed. (UUM-47681)

  • Graphics: Make CullingParameters.viewID 64 bits. (UUM-146214)

  • HDRP: Clear coat materials produce screen-space reflections when the clear coat value is 0 in Forward Only Lit Shader Mode. (UUM-84980)

  • Package Manager: Fixed DirectoryNotFoundException thrown when the sample path is invalid. (UUM-141115)

  • Package Manager: Fixed issue where install progress spinner for a selected package disappears when another package is selected. (UUM-139184)

  • Package Manager: Fixed NullReferenceException when the sample is missing the path property. (UUM-137672)

  • Scripting: Added a defensive check / fix for stale GC handles during domain reload. (UUM-122598)

  • Serialization: Fixed crash where WeakReferences were being destroyed off of the main thread, which contended with Mon's GC assumptions about WeakReferences only being freed from the main thread. This fixes an eventual crash inside the Garbage Collector. (UUM-143324)

  • SRP Core: Fixed an issue where Camera.RenderToCubemap didn't capture Canvas geometry for the first face of a cubemap. (UUM-140991)

  • Text: Fixed text disappearing in EditorGUILayout.TextArea when the field contained a large amount of text (roughly 16,000 characters or more). (UUM-146126)

  • UI Toolkit: Fixed a one-frame glitch where a world-space UIDocument could briefly appear mis-placed when shown again after being hidden with display: none. (UUM-119563)

  • UI Toolkit: Fixed an issue where Object Picker window breaks when it is interrupted by a domain reload. (UUM-144436)

  • Windows: Fixed On Demand Rendering related issues when hiding and resizing embedded window. (UUM-102668)
