Add a new Pause Menu UI (UXML, USS, TSS, asset/meta) and related UI folder metadata. Add new terrain assets and TerrainData files, plus lighting settings for the 2.5d demo scene. Import a new character model (X Bot.fbx) with its importer meta and new characters folder. Update SampleScene and LFS pointers, and refresh render pipeline settings (Mobile RP & URP global settings) and project/package settings. Tweak multiple material files: align _Color with BaseColor, add SHADOWCASTER to disabled shader passes for Ellen materials, and assign a missing main texture for Vincent_Hero_High_diffuse.
Bulk-updates Mixamo material assets under Assets/Mixamo Animations to the Universal Render Pipeline material layout (serializedVersion -> 8). Shader references were replaced with the URP shader GUID, an AssetVersion MonoBehaviour block was added, and many new material properties were added/normalized (BaseMap/_BaseColor/_SpecColor, SpecGlossMap, unity_Lightmaps/unity_ShadowMasks, various floats/ints like _Smoothness/_Cull/_Surface/_WorkflowMode, disabled MOTIONVECTORS pass, etc.). ProjectSettings.asset was also modified (likely to reflect the pipeline update). These changes align materials with URP serialization and rendering expectations.
Add a full Unity project scaffold: Input System actions (.inputactions + meta), SampleScene and scene meta, URP render pipeline and profile assets, TutorialInfo (scripts/icons), a Readme LFS pointer, ProjectSettings (audio, graphics, input, quality, XR, etc.), and Packages/manifest.json. Sets up default player and UI input mappings, rendering settings, and editor/project configuration for the project.
