What's Changed

About SplashEdit Page

• New About SplashEdit window in the PlayStation 1 menu
• Added supporters section

SplashEdit Control Panel Performance

• Fixed expensive status checks running on every repaint in the control panel

PSX Timeline Editor Fixes

• Skin Anim event lane now shows by default when available, matching expected event-lane behavior
• Right-click on Add Track row now opens the Add Track menu
• Right-click in event lanes now supports creating Audio Events and Skin Anim Events at cursor frame
• Delete and Backspace now correctly delete selected events (audio and skin anim), not just keyframes
• Added Delete Selected Event option in the context menu

What's Changed

CD-DA Music Tab (wildmonkeydan, Bandwidth)

• New Music (CD-DA) tab in the SplashEdit Control Panel for managing disc audio tracks
• Add, remove, and reorder audio clips (MP3, WAV)
• Drag and drop support from the Unity Project window
• Track list persisted in EditorPrefs per-project
• Tracks are written as audio tracks in the ISO XML starting at track 2
• Disclaimer shown that CD-DA only works with ISO builds

Platform Flag on Objects (Bandwidth)

• New Is Platform toggle on PSXObjectExporter
• When enabled, all boundary edges of nav regions generated from this mesh allow walkoff
• Exposed in the PSXObjectExporter inspector alongside collision settings

Walkoff Zones (Bandwidth)

• New PSXNavWalkoffZone component for marking individual nav region edges as walkoff
• Place the volume along boundary edges; any edge whose midpoint falls inside the zone gets the walkoff bit set
• Visualized as an orange wireframe box in the Scene view
• Collected automatically at export time from the scene

Nav Region Builder Updates (Bandwidth)

• Tracks boundary edges (edges with no portal neighbor) via a per-region bitmask
• Correctly remaps boundary edge flags when polygon winding is reversed
• ApplyPlatformFlags sets the platform flag and walkoff mask on regions whose centroid falls inside a platform exporter's bounds
• ApplyWalkoffZones sets individual walkoff bits on boundary edges inside walkoff zone volumes
• Binary export writes flags and walkoffEdgeMask instead of the former two padding bytes

Inspector Changes (Bandwidth)

• Smooth Normals toggle now visible in the PSXObjectExporter inspector

Thanks

Hotfix

• Split up VRAM and SPU data to separate files from the splashpack
• Backspace now works in PSX Timeline EditorWindow to delete characters within input fields

What's Changed

Skinned Mesh Animations

• New PSXSkinnedObjectExporter component — attach to any SkinnedMeshRenderer to export bone-animated characters to PS1
• Hard skinning (one bone per vertex) with configurable sampling rate (1–30 FPS, default 15)
• Supports Humanoid and Generic animation clips — auto-detects and reimports models as Humanoid when needed
• Per-frame bone matrices baked at export time; sub-frame interpolation at runtime for smooth playback at any framerate
• Custom inspector shows bone count, frame counts, and estimated PS1 memory usage
• Limits: 16 skinned meshes, 64 bones, 16 clips per mesh

Skin Anim Events

• Cutscenes and animations can now trigger skinned mesh animations at specific times during playback
• Each event specifies: target object, clip name, loop flag
• Maximum 16 events per cutscene/animation

Timeline Editor

• New visual editor window for animations and cutscenes (PlayStation 1 → Timeline Editor, or double-click any clip asset)
• Transport controls (play/pause/stop), playhead scrubbing, zoom and pan
• Color-coded tracks: Camera (cyan), Object (green), UI (magenta), Rumble (gold)
• Add Track menu auto-discovers scene objects, canvases, and UI elements
• Right-click context menu for adding/deleting keyframes and changing interpolation
• Multi-select keyframes, drag to reposition, Undo support
• Audio event and skin anim event lanes
• Live scene view preview with camera driving, object transforms, and skinned mesh poses

Controller Rumble

• New Rumble Small and Rumble Large track types for cutscenes and animations
  • Small motor — high-frequency on/off (sharp impacts)
  • Large motor — variable speed 0–255 (sustained rumble)
• Requires DualShock controller or emulator rumble support

Navigation Mesh Overhaul

• 8 new parameters exposed on PSXPlayer (previously hardcoded):
  • Partition Method (Watershed / Monotone / Layer)
  • Min Region Area, Merge Region Area, Max Simplify Error, Max Edge Length
  • Detail Sample Distance, Detail Max Error, Max Plane Error
• Three quick presets: Indoor, Terrain, Multi-Level
• Detail mesh interior vertices now included in floor plane fitting — much better height accuracy on terrain
• Nav builder UI merged into the PSXPlayer inspector with build/clear/preview buttons, statistics, PS1 budget warnings, and scene view gizmos
• Separate Nav Region Builder window removed

Mesh Export

• New SmoothNormals toggle — disable for flat/faceted shading on a per-object basis

Scene Export

• Splashpack binary format updated (v19) with skinned mesh data support
• All nav parameters forwarded from PSXPlayer to the builder during export

What's Changed

macOS Support

• macOS toolchain detection — checks common install locations (~/mipsel-none-elf/bin, /opt/homebrew/bin, /usr/local/bin) and tries both mipsel-none-elf and mipsel-linux-gnu tool variants
• macOS build PATH fix — Unity on macOS launches bash with a restricted PATH; build commands now prepend toolchain directories automatically
• macOS PCSX-Redux download — adds dev-macos-arm platform variant for Apple Silicon

Mesh Export

• Vertex color modes — new VertexColorMode setting on PSXObjectExporter:
  • Baked Lighting (default) — pre-bakes scene lighting into vertex colors
  • Flat Color — all vertices get a single configurable color
  • Mesh Vertex Colors — uses vertex colors from the mesh (e.g. painted in Blender)

Cutscenes

• CameraH track type — animate the PS1 projection H register (FOV) in cutscenes
  • Editor slider with live FOV preview (H ↔ vertical FOV conversion)
  • "Capture from Scene View" reads the current Scene View FOV and converts to H
  • Scene View FOV is saved/restored during cutscene preview

Scene Export

• Per-room cells + indexed portal references — rooms are subdivided into spatial cells and portal connections are stored per-room for faster runtime traversal
• Splashpack v17 binary format with cell and portal reference data
• Dynamic object BVH fix — AABB is shifted correctly when objects are repositioned

Control Panel

• Room Debug Overlay build setting — renders all room triangles in per-room colors for culling diagnosis (passes ROOMDEBUG=1 to Makefile)
• IsCameraTrack helper property on PSXCutsceneTrack for cleaner track type checks
