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.

Verification

source tools/web/emscripten-env.sh
cmake --build build_web_blender6 --target web_engine -- -j8
bash tools/web/install-web-engine-assets.sh
npm --prefix web ci
npm --prefix web run typecheck
npm --prefix web run lint
npm --prefix web run build
npm --prefix web run test:browser

See docs/CURRENT_EXECUTION_PLAN.md for the current task order, docs/PROJECT_STATUS_AND_NEXT_WORK.md for the implemented scope, and docs/BLENDER_5_2_WEB_FEATURE_PARITY.md for the long-term Blender parity ledger. The atomic full-product work breakdown is in docs/BLENDER_5_2_FULL_PARITY_WBS.md.

The release contract and explicit non-goals are defined in docs/WEB_BLENDER_MODELER_V1_SCOPE.md.
