* fix(viewer): guard TextureNode updates against null textures three's override-material passes (shadow, prepasses) copy per-object texture slots onto shared materials whose cached per-mesh node graphs can disagree about a slot's presence; when a graph with a TextureNode pulls a null slot, the exception kills the whole render pass and the scene goes black. Patch TextureNode.prototype.update to skip null values (with a throttled warning) so the slot just renders textureless for a frame and recovers. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * revert(viewer): drop the always-on neutral displacement texture Giving every standard material a displacement texture put displacement TextureNodes into the shared shadow/prepass override graphs; in scenes mixing preset materials with GLB item materials (no displacementMap), an item's shadow render can hit a cached graph that expects the texture and pull null — build-order dependent, which is why it broke many-but-not-all projects at open right after the release. The TextureNode fallback guard covers the original paint-hover crash (black texel = zero displacement), so the broad neutral-texture approach is retired.

@pascal-app/viewer
3D viewer component for Pascal building editor.
Installation
npm install @pascal-app/core @pascal-app/viewer @pascal-app/editor @pascal-app/nodes
Peer Dependencies
npm install next react react-dom three @react-three/fiber @react-three/drei lucide-react zustand
What's Included
- Viewer Component - WebGPU-powered 3D viewer with camera controls
- Node Rendering Runtime - Registry-driven dispatch for node renderers supplied by
@pascal-app/nodes - Post-Processing - SSGI (ambient occlusion + global illumination), TRAA (anti-aliasing), outline effects
- Level System - Level visibility and positioning (stacked/exploded/solo modes)
- Wall Cutout System - Dynamic wall hiding based on camera position
- Asset URL Helpers - CDN URL resolution for models and textures
Usage
import { loadPlugin } from '@pascal-app/core'
import { builtinPlugin } from '@pascal-app/nodes'
import { Viewer } from '@pascal-app/viewer'
import { useEffect, useState } from 'react'
const registryReady = loadPlugin(builtinPlugin)
function App() {
const [ready, setReady] = useState(false)
useEffect(() => {
void registryReady.then(() => setReady(true))
}, [])
if (!ready) return null
return (
<div style={{ width: '100vw', height: '100vh' }}>
<Viewer />
</div>
)
}
Load the built-in plugin once, before mounting any viewer. Without it, the registry has no node
definitions and scene nodes cannot render. Host-provided plugins use the same loadPlugin API.
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)
