A Real Two-User Feather Engine Collaboration Session

I recorded a real host-and-editor collaboration session in Feather Engine, the local-first open-source 3D game engine.

Project-wide, not viewport-only

The shared state follows the open project across the engine while both people work.

• Viewport and scene hierarchy changes.- Object transforms, components, and Inspector fields.- Blueprint graph changes.- Selections and live editing presence.## Host-owned by design The desktop owner starts the session with their own ngrok authtoken and shares the invite. The host remains authoritative for saving, Play mode, and local filesystem work, so collaboration does not require an always-on Feather cloud backend. ## Watch the real session The new website demo shows the session setup, role roster, and live editing workflow from start to finish: https://feather-engine.com/#collaboration ## Current boundary This remains an experimental desktop feature. Use source-controlled project copies and keep backups while the collaboration protocol and project format continue to evolve.
