Camera Animation: position the camera and save keyframes via the camera icon; moving the timeline with CTRL mirrors camera movement during playback. Tracking Camera - turn a WebXR-compatible smartphone into a virtual camera: connect via QR and one-time code, then record and overwrite camera motion directly on the timeline. LiteUI Mode reduces UI blur and transparency for low-end devices. Offline Mode lets the editor launch without internet after the first run. Plugin System - create custom JS plugins to extend BDE.
