Blender engine

Read this when building or changing the Blender worker or its Three.js frame presenter. This package contains Blender itself, compiled to WebAssembly, its worker, Python session, message protocol and tab-side handle. It is independent of the editor host and game runtime.

The package is GPL-3.0-or-later. Preserve LICENSE, including all upstream notices. No repository-wide license overrides this package's license.

Build and check

From the repository root, install the locked dependencies and run:

npm ci
npm run typecheck
npm run build:blender-three

Run these commands through the active World when working in the Volter development environment. The browser typecheck has no monorepo aliases and no Node ambient types. The presenter build emits its standalone module and sky worker under this package's dist/release/ directory.

The checked-in WASM files are prebuilt. Their exact upstream source, recipe and artifact hashes are in wasm/BUNDLE.json. Building the presenter does not rebuild or verify Blender itself. The corresponding Blender source remains in the separate volter-ai/blender fork.

Distribution

The corresponding source is public at volter-ai/blender, and wasm/BUNDLE.json pins its snapshot, release and artifact hashes. Publication still requires the repository release checks; a successful local build alone is not sufficient.

The import record identifies the original source revision and hashes. Runtime, protocol and artifact bytes are preserved; legacy internal wire markers and Blender build identifiers are intentionally not renamed independently of their producers and consumers. Package identity and build configuration use the public repository.

Benchmark/oracle tools remain at the pinned source revision until their inputs and execution dependencies are migrated. Their old results are not verification of a new editor release. The original editor still uses its existing package; consumer cutover is tracked in the repository's WORK.md; do not create a second independently edited implementation.
