Unreal Sequencer Automation

Version: 3.1.1 Last Updated: 2026-10-09 Dependencies: Unreal Engine 5.8+, UE 5.8 native MCP (HTTP, port 8000) Major Updates: UE 5.8 migration, camera cuts, channel initialization, ImagePlate 100%

Preflight first (2026-09-08): before the first build step of any approved plan, run the unreal-project-preflight skill (ue_preflight.py --live --features <list> --plan-block) so plugins and project settings this skill depends on are enabled in ONE restart. Mid-task "class not found / plugin not enabled" errors go back to that Step 0, never to a runtime toggle.

CRITICAL DISCOVERIES

1. Camera Cut Tracks - SOLVED

The API that doesn't exist: add_camera_cut_track() - Use generic add_track() instead!

2. Transform Channels - SOLVED

Empty channels are NORMAL! Channels don't exist until you add the first keyframe.
