Fix Unity 7 assembly and lighting API compatibility - #1449
Conversation
📝 WalkthroughWalkthroughThe changes add Unity-version-specific assembly compatibility helpers and use them in assembly discovery and compilation. Light-baking status and settings now use Unity-version-aware helpers for realtime GI and lightmapper access. ChangesUnity API compatibility

Record Undo for the setting that changes.
On Unity 7, this line changes EditorGraphicsSettings.defaultLightBaker. SetSettings records Undo only for lightingSettings and later marks only that asset dirty. Undo therefore cannot restore the light baker selected by bake_set_settings. Record the graphics-setting change through an appropriate Unity Undo mechanism, or state that this setting cannot be undone. (docs.unity.com)

Unity 7000.0.0a7 reports UAC0005, UAC0007, UAC0020 and obsolete lighting API warnings in these paths. The assembly shim currently accepts only an
Assembly[]return type, so it rejects Unity 7'sIReadOnlyList<Assembly>API and falls back toAppDomain. Runtime compilation also loads emitted assemblies outside Unity's assembly load context and usesAssembly.Location, which can be empty for stream-loaded assemblies.This change uses Unity's assembly enumeration, loading and path APIs through
UnityAssembliesCompaton Unity 7, and updates the remaining glTF fallback scan. Lighting tools use the Graphics Settings light baker on Unity 7 and retain optional access to legacy Enlighten settings through reflection.Compatibility:
UNITY_7000_0_OR_NEWER. Earlier Unity versions retain the existing enumeration shim,Assembly.Load,Assembly.Location, andLightingSettings.Lightmapperpaths.lightmappervalue on Unity 7 uses the newLightBakerenum (ProgressiveLightBaker/UnityComputeLightBaker); older versions retain their existing enum names.Confirmed against upstream
betaat ef713af. Its ToolDiscoveryService scan was already removed, so this PR does not duplicate that fix.Validation: the same compatibility edits, backported to v10.2.0, compiled successfully in an existing Unity 7000.0.0a7 project, with the listed compiler warnings absent and the MCP connection restored after reload. The beta package as a whole was not installed in that project. Older Unity Editors, light baking, and runtime-code execution were not exercised; no additional test suite was run.
