Two readiness fixes surfaced by the first successful headless bake of a heavy scene (which exported with 33 items missing): - The 180-FRAME give-up cap silently assumed display-rate frames. The bake page's timer-driven loop (?disable=draw) runs those frames in ~3.6s — shorter than a cold item-model download — so the cap fired and the export raced ahead of real content. New `sceneReadyMaxWaitMs` Viewer prop replaces the frame cap with a wall-clock one on hosts whose frame cadence is decoupled from time; default frame behavior unchanged for interactive surfaces. - hasPendingSceneBuildWork now skips UNREACHABLE dirty nodes: orphans whose parent doesn't list them in `children` (or parentless non-roots) never render — every renderer enumerates the parent's children array — so no system ever builds them or clears their mark. Observed in prod scene data (two dangling windows parented to a level that doesn't list them): they held every bake of that scene to the full readiness cap. Validated: the 200+-item office scene with ?disable=draw settles organically in ~2s and exports the complete artifact; a one-shot 504'd item is now WAITED for through its retry instead of racing the cap.

Usage
import { Viewer, useViewer } from '@pascal-app/viewer'
import { useScene } from '@pascal-app/core'
function App() {
return (
<div style={{ width: '100vw', height: '100vh' }}>
<Viewer />
</div>
)
}
Custom Camera Controls
import { Viewer } from '@pascal-app/viewer'
import { CameraControls } from '@react-three/drei'
function App() {
return (
<Viewer selectionManager="custom">
<CameraControls />
</Viewer>
)
}
Viewer State
import { useViewer } from '@pascal-app/viewer'
function ViewerControls() {
const levelMode = useViewer(s => s.levelMode)
const setLevelMode = useViewer(s => s.setLevelMode)
const wallMode = useViewer(s => s.wallMode)
const setWallMode = useViewer(s => s.setWallMode)
return (
<div>
<button onClick={() => setLevelMode('stacked')}>Stacked</button>
<button onClick={() => setLevelMode('exploded')}>Exploded</button>
<button onClick={() => setWallMode('cutaway')}>Cutaway</button>
<button onClick={() => setWallMode('up')}>Full Height</button>
</div>
)
}
Asset CDN Helpers
import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'
// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'
// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)
Features
- WebGPU Rendering - Hardware-accelerated rendering via Three.js WebGPU
