Changelog

🎁 Added

• Runtime mesh morphs API - Mesh.AddMorph() lets you add morph targets (position and normal deltas) to meshes at runtime

• Mesh to model dialog now shows options for configuring collision when converting meshes

• Mirror tool can now be repositioned after placing, similar to the clipping tool

• Bounding box snapping - bounding boxes now snap to grid by default

• ResourceWriter.AddExternalReference for referencing external resources (e.g. materials from model resources)

• Model inspector has useful info about meshes

• DragEvent constructor is now public, allowing custom input systems to forward drag events through the UI pipeline. Thanks @dictateurfou!

• Viewport background color is now customizable in editor preferences. Thanks @boxrocket6803!

• Cursor page rework in project settings - now shows all system cursors you can override and auto-adds cursor images on upload

🧼 Improved

• Audio system refactored with a lock-free triple-buffer threading model, eliminating previous crash-prone locking

• Steam Audio effects compiled directly into the engine with AVX SIMD, roughly doubling spatial audio performance and removing the external DLL dependency

• Physics queries no longer allocate heap memory for multi-result queries, using thread-local buffers instead

• Physics callback virtual dispatch overhead eliminated by using concrete types and caching body type lookups

• Rendering performance improved by removing redundant render attribute duplication, unnecessary performance trace scopes, and unused render pipeline stats

• LOD clutter screen coverage now calculated per-model instead of per-tile for more consistent results

• Media recording now captures at the end of the render pipeline, including overlays

• VMDL writer now also saves the PHYS block when exporting models

• Physics resource system modernized to use proper resource handling, enabling vphys resource previews

• Steamworks SDK and steamclient updated to latest version, which should reduce network packet issues

• Default video settings aligned between native and managed - MSAA now defaults to 4x (was 16x native), fullscreen defaults to borderless

• Grass rendering looking super dark in places

• Player display names now resolved locally, instead of by the host. Thanks @Matt9440!

• Compile timeout raised from 60 to 120 seconds for large projects. Thanks @MrBrax!

• Props now ignite their gibs when a burning prop breaks. Thanks @Xenthio!

• Scene wheel zoom now treated as camera movement. Thanks @TheGWOO!

• Dragged decal game objects now assigned proper names. Thanks @wheatleymf!

🪛 Fixed

• Fixed morph target names and categorization when importing models

• Fixed incorrect FBX morph normals

• Fixed chat network messages not registering on non-host clients

• Fixed platform settings property getting cut off in the editor

• Fixed custom shaders having tinted wireframe

• Fixed material override not clearing properly when applying model material groups. Thanks @Matt9440!

• Fixed Doo visual scripting not showing return assignment when function has no arguments. Thanks @PolEpie!

• Fixed viewport flashing on Linux/XWayland by suppressing Qt paint cycle. Thanks @AlexTrebs!

• Fixed pointlight shadows breaking when shadow resolution decreases. Thanks @boxrocket6803!

• Fixed missing hover styles when dragging items over folders in asset browser. Thanks @Matt9440!

• Re-enabled 'None' anti-aliasing option. Thanks @Mykol-Word!

• Editor now opens on the correct monitor. Thanks @boxrocket6803!

• Splash screen now always starts centered. Thanks @boxrocket6803!
