Blender Web WASM

Blender 5.2-based Web editor runtime with a React/Three.js frontend, a native Blender Main compiled to WebAssembly, versioned browser protocols, OPFS/IndexedDB storage, and desktop/WASM round-trip tests.

The current browser baseline is Chromium only. The release browser suite covers both the main-thread WebGL renderer and the OffscreenCanvas Worker renderer. Firefox and WebKit are intentionally outside the current test and release scope.

Layout

• blender-5.2.0/: corresponding Blender source with the WebEngine integration.
• web/: frontend, Worker clients, protocols, Playwright tests, and local runtime assets.
• tools/web/: fixture, golden, build, and offline-release tooling.
• tests/: .blend fixtures and semantic golden data.
• docs/status/: machine-readable and task-specific parity ledger.
