THIRD_PARTY_NOTICES.md

Third-party software

All versions are pinned exactly in package.json. License texts of every package bundled into the application are copied to public/licenses/ and ship with the production build. No proprietary, commercial-only, source-available or custom-licensed packages are used.

Interoperability data

• The app is an independent, clean-room implementation. It contains no source code, icons, themes, text, startup files or other assets from Blender (GPL-2.0-or-later).
• For file and scripting compatibility (.blend import, bpy-style scripts), some generated tables (src/nodes/shader/data.gen.ts, src/geonodes/data.gen.ts, src/geonodes/data-fields.gen.ts, src/io/blend/nodeprops.gen.ts, compositor node data) list node, socket and property names, identifiers, enum items and default values of the public bpy API. These are interface facts needed to read and write compatible data, not expressive code; they are flagged here for legal review.
• Test fixtures in tests/fixtures/ (.blend, .glb, .fbx, .usd*, .abc, …) were generated for this project by the scripts in the same folders or written by hand.
• "Blender" is a trademark of the Blender Foundation. It is used only to name the .blend file format; this project is not affiliated with or endorsed by the Blender Foundation.
