unreal-blueprint-automation

Version: 2.0.2 Last Updated: 2026-09-08 Dependencies: Unreal Engine 5.8+, UE 5.8 native MCP (HTTP, port 8000), VibeUE plugin (optional) Status: Production Ready

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.

Overview

Automate Blueprint creation, component addition, property configuration, and compilation in Unreal Engine 5.8 using the proven phased execution pattern that prevents crashes and timeouts.

Key Discovery: Blueprint compilation triggers async validation that blocks subsequent Python operations. Using Silent Execution (no code after compilation) eliminates crashes.
