2023.1.9f1 Release Notes

API Changes

• Build Pipeline: Added: Build Pipeline: Added "Dedicated Server optimizations" option that strips all shaders from Dedicated Server builds.

• SRP Core: Added: Added callbacks when RenderPipeline is created or disposed. (UUM-20646)

Fixes

• Animation: Fixed memory leak in asset import process. (UUM-33327)

• Build Pipeline: Fixed incorrect AssetBundle dependencies are generated. (UUM-43175)

• Build System: Clang fails when header file mtimes are updated and a precompiled header isn't regenerated. (UUM-44429)

• Core: Fixed wizard asking to upgrade when not required.

• Core: ForEach jobs no longer allocate internal data using the TempJob allocator, eliminating one source of 'possible leak' warnings for long-running jobs. (UUM-45532)

• DX12: Fixed sub meshes not being visible sometimes in ray tracing effects on AMD GPUs. (UUM-44073)

• Editor: Calculate Mask value fix for last layer selection in RenderingLayerMask. (UUM-29344)

• Editor: Clicking a foldout with Alt held will now set all child foldouts to the same expanded state when they are bound to SerializedProperty.isExpanded. (UUM-36151)

• Editor: Ensured ExecuteInEditMode warning when entering playmode will fit in a dialog box. (UUM-44500)

• Editor: Fixed an issue when using -nographics command line switch in MacOS editor, causing asset importer process to not work properly. (UUM-44347)

• Editor: Fixed an issue where it was not possible to bind a shortcut to Mouse0 in the Shortcut Manager Window. (UUM-43118)

• Editor: Fixed case where variant Inspector context was not disabled as intended. (UUM-44331)

• Editor: Fixed control shortcut modifier (^) was not been displayed, when introduced inside a custom menu Window for MacOS & Linux platforms. (UUM-40686)

• Editor: Prevent blendshape normals calculation when mesh normal is set to Calculate and blendshape normals is set to None. (UUM-36071)

• Editor: Prevent C4D native importer warnings if a project has its own C4D ScriptedImporter. (UUM-36242)

• Graphics: DrawProcedural family of functions now also work when shaders want vertexbuffers. (UUM-32295)

• Graphics: Fixed a crash (or memory leak) caused when using AABBs procedural geometries in a RayTracingAccelerationStructure. (UUM-43293)
