Wonderland Engine 1.5.0

WebGPU support with full WebGL2 feature parity, probe volume scenarios, runtime baking, audio resources, and particle effect JS API.

Physical Clear Coat 

Clear coat support has been added to the default Physical pipeline.

Changelog 

Editor

• Add new probe volume scenario resource
• Split probe volume voxelization and baking. You can now see the voxelization result before baking.
• Make probe volume baking cancellable. If restarted, resumes from where it was cancelled.
• Speed up scene voxelization for probe volume baking
• Allow selecting WebGPU-only as rendering API
• Make shadow map size configurable, clamped at runtime to supported size
• Show more fine-grained GPU timings in the Profile view
• Optimize Scene View debug visualization rendering
• Allow switching between projects in a workspace from the Scene Outline
• Fix some cases of stale data after switching projects
• Rework undo/redo to work correctly when switching projects
• Display a popup when a project fails to load
• Add project file export and import. Exporting creates a new .wlp with the selected objects and all referenced resources. Importing merges an exported .wlp into the current project.
• Add new Particle Effect resource. Can currently be used from the new ParticleEffectComponent JS component for programmatically creating effects. A no-code effect creation UI is planned for a future version.
• Add new Audio Clip resource. Audio files will get deployed as separate files alongside the packaged .bin.
• Allow filtering collision and physics debug visualization in Scene View to selected objects only
• Add Install button to Plugin view for simple installation of bundled plugins
• Add loadUncompressedImagesAsBitmap runtime setting for loading uncompressed images as ImageBitmap (instead of HTMLImageElement etc.)
• Add deferSkinningCompilation rendering setting to defer skinning shader compilation to their first use
• Fall back correctly to importPhysicalAsPhongMaterials editor setting on older projects
• Fix regression when dropping assets onto objects
• Convert material colors to sRGB if necessary
• Minimize shader recompilations on pipeline changes
• Handle animations with an empty track list
• Reset all transforms when disabling animation preview
• Eliminate race condition while compressing images
• Fix undo of an operation that created a resource
• Use correct offset when scroll-to-bottom is active in Console view
• Improve path handling for projects on different Windows drives
• Make file watching more robust on all operating systems
• Handle some invalid component edge cases more gracefully
• React to changes to app.js and index.js
• Fix a rare crash when editing text inputs with large strings
• Fix crash when toggling enableRuntimeGltf
• Fix several webserver-related crashes
• Enable crash handling in –windowless mode
• Add “Replace references” tool in Resource View

Engine

• Implement WebGPU rendering backend with full feature parity
• Avoid superfluous skinned mesh updates with multidraw enabled
• Package probe volume scenarios as delay-loaded .bin files
• Fix morph targets sometimes targeting the wrong mesh
• Initialize cloned animation components without skins
• Eliminate artifacts on Meta Quest when enabling usePreZ
• Use albedo alpha value for Physical shader output
• Add CLEARCOAT feature to Physical shader for rendering glossy transparent materials like car paint
• Render multiple-scattering in Physical shader with environment probes
• Optimize Physical shader for mobile GPUs
• Skip some vertex shader work for meshes with scaling 0
• Improve skinning shader compatibility with some older mobile GPUs
• Fix several browser warnings

Runtime

• Bundle all WebGPU-enabled variants of the runtime
• Use correct threaded runtime when WebGPU is enabled
• Fall back to WebGL2 runtime if WebGPU is not supported or initialization fails
• Use multithreading for glTF loading to reduce hitching and improve performance when loading multiple files. Can be toggled via GLTFOptions.async.
• Pass embedded glTF image blobs directly to the browser for decoding, skipping expensive base64 conversion
• Add support for WebXR layers. Enable by requesting the layers WebXR feature.
• Use WEBGL_multisampled_render_to_texture with WebXR layers on Meta Quest
• Fix collider visualization

Editor API

• Rename project to workspace
• Add workspace.projects[] for accessing per-project data
• Add tools.saveProject()
• Add tools.getComponentTypes()
• Add ui.inputTextPassword()
• Add several missing type declarations
• Eliminate editor hang when calling tools.packageProject()
• Fix wrong values returned from tools.computeMeshBounds()
• Fix deletion of referenced resources crashing the editor
• Hide some non-enumerable properties

JS API

• Add Environment.requestBake() for baking environment from the current sky material
• Add GLTFOptions.generateSimpleTangents to generate trivial tangents instead of using mikktspace. Speeds up loading, but might produce rendering artifacts.
• Add new ParticleEffectComponent for spawning and rendering instanced particle effects
• Add new ParticleEffect resource
• Add new AudioClip resource
• Add Resource.origin to get the scene a resource was loaded from
• Add ResourceManager.loadedFromScene() to query all resources loaded from a given scene
• Add ResourceManager.all() to query all alive resources
• Add Prefab.destroyResources() for destroying all resources loaded from a scene
• Add AnimationGraphManager for creating 1D-blend graphs from multiple animations
• Add AnimationGraph.setPlaybackSpeed() for controlling playback speed of individual animation graph samplers
• Add ViewComponent.getDirectionForScreenPosition() to get a view-space direction for a set of canvas coordinates (e.g. for raycasting mouse clicks)
• Add visualize setting to CollisionComponent and PhysXComponent to control the debug visualization visibility per component
• Make toggling LightComponent.shadows actually update shadow rendering
• Fix ViewComponent.getViewport() returning invalid data
