Changelog

Major expansion of the C# scripting API from 6 service classes to 11. Every engine system now has a dedicated, documented class. Official documentation website launched at prometheonstudio.com.

• Added Environment class — time of day, weather, fog, wind, sky color
• Added Lighting class — ambient, sun, bloom, point lights, shadows
• Added Physics class — gravity, forces, impulses, material properties
• Added World class — create, move, rotate, scale, color, clone objects
• Added Camera class — FOV, shake, view mode, distance, look target
• Added Player class — teleport, skin colors, speed, jump power
• Expanded Audio and Particles classes with new methods
• Added Debug.Assert for runtime assertions
• All commands route through updated runtimeEngine.js dispatch layer
• Full API reference website shipped (prometheon-script-api.html)

• Fixed walk animation — setHumanoidMotion now called every frame from loop()
• Rebuilt Ctrl+drag free-look camera for Mac trackpad (no prior click required)
• Fixed permanently latching _freeLookActive flag that locked camera orientation
• Third-person chase camera now trails behind player with exponential lerp smoothing
• Context menu clamped to viewport — no longer clips off-screen
• Fixed player context menu showing no actions (id suffix check was too broad)
• Sprint FOV boost, bob, and shoulder micro-sway added to animation system

• Complete humanoid character rebuild — ears, belt strip, ankle cuffs, natural arm angle
• Shared per-type materials on group.userData.materials for runtime recoloring
• ServerStorage system — hide objects from scene without removing from tree
• moveToStorage, moveToWorkspace, cloneFromStorage APIs added
• Default editable "Character" template created in storage at engine init
• Trackpad two-finger tap context menus added to File Explorer and Scene Tree
• Play-mode camera improved with Ctrl+drag freelook support

• File Explorer rebuilt with drag-and-drop, context menus, and live preview
• HUD system added — runtime UI overlay layer
• Initial humanoid character system introduced
• Baseplate physics — special case cuboid(200,0.05,200) floor collider for Rapier
• Scene tree actions wired: FileExplorer → PanelHost → EditorShell → engine

• Full Scene Tree panel with live sync to Three.js scene graph
• Engine API surface expanded — getNodeById, objectMap, emitSceneUpdate
• Texture map support: albedo, normal, roughness, metalness, emissive
• PBR material system wired to Scene Tree inspector

• Animation editor rebuilt with keyframe timeline and curve editor
• Blend tree support for multi-state animation mixing
• Per-bone override channels added
• Animation preview in viewport while editing

• Sequence timeline editor for scripted events and cutscenes
• Custom terrain shader with multi-layer blending
• Physics inspector panel — live collider visualization and property editing
• Prefab variant system — override individual properties without breaking inheritance

• PBR material editor — roughness, metalness, emissive, normal map channels
• Runtime profiler — draw calls, triangle count, physics step time, frame budget
• Post-processing stack: bloom, tone mapping, vignette
• Environment inspector — ambient, fog, sky, and HDR environment map controls

• Navigation mesh baking — bakeNavMesh, findPath, addNavAgent APIs
• Audio bus system — master, music, and SFX channels with independent volume
• Curve-based particle emission — emission rate and size driven by animation curves
• WebGL export target added to the build pipeline

First public update. Foundational engine systems established on top of the initial Elden Engine 3D core.

• Audio system — Web Audio API integration, sound effects and music streaming
• Particle system — explosion, fire, smoke, and magic presets
• Environment system — daylight cycle, weather presets, fog control
• Core bug fixes across physics, scene graph, and ECS initialization
• C# runtime host established — dotnet 8 script compilation pipeline
