- Guard _buildCache in merged-outline-node against stale/disposed
Object3D refs that cause TypeError on .id access during render
- Reset children array when duplicating roofs to prevent inconsistent
parent-child relationships (matching existing stair behavior)
- Use obj?.parent check in EditorOutlinerSync to ensure objects are
still in the scene graph before adding to outliner arrays
- Resume temporal state on parse failure to prevent undo/redo freeze
Closes#232
The WebGPURenderer needs its backend initialized before any direct
`.render(scene, camera)` call. The commented-out `// renderer.init()`
said "Only use when using <DebugRenderer />", but the non-debug path
also calls direct render from the post-processing fallback
(post-processing.tsx:318), which throws "Renderer: .render() called
before the backend is initialized" on any browser that falls back to
the WebGL2 backend.
Switching the gl factory to an async function and awaiting init()
before returning is safe in both backends (init() is idempotent and
the async factory is a supported @react-three/fiber v9+ pattern), and
prevents the error in WebGL2 fallback.
`RenderPipeline`, SSGI, and the denoise TSL node imported from
`three/webgpu` and `three/tsl` are all WebGPU-only. On a browser
without `navigator.gpu`, the WebGPURenderer falls back to WebGL2, and
attempting to build the TSL post-processing pipeline either throws or
produces broken output — the scene renders for a few frames, then
goes black as the 3-attempt retry loop fights the direct-render
fallback path in `useFrame`.
This sets `hasPipelineErrorRef.current = true` at pipeline setup time
when `navigator.gpu` is undefined, so `useFrame` takes the existing
direct `renderer.render(scene, camera)` path exclusively and never
tries to build the broken TSL pipeline.
No behavioural change in WebGPU mode — the guard only fires when the
WebGPU API is literally not exposed by the browser. The rare edge
case of `navigator.gpu` being defined but device creation failing at
runtime still falls through the existing try/catch unchanged.
* feat: add polygon movement support to editor and implement dedicated move tools for walls, slabs, and ceilings
* feat: add uv2 attribute to ceiling and slab geometries for lightmap support
* Fix curved wall miters and align roof position sliders
* Fix wall measurement label and extension anchors
* Fix WebGPU renderer initialization order
* fix(editor): scope wall movement to the selected level
