Migrate from Unreal to Summer Engine

You can migrate your Unreal project to Summer Engine. The workflow: have the AI use shell and tools to research your existing project, create a migration plan, then rebuild in Summer Engine. Relatively fresh projects can often be done in one pass; larger projects need more planning.

Step 1: Prepare Your Unreal Project

1

Document your project

Have a clear picture of your levels, Blueprints/scripts, and assets. The AI will need to understand your structure
2

Download Summer Engine

Visit summerengine.com and download
3

Create a new Summer Engine project

Start fresh in Summer Engine. You’ll rebuild, not import

Step 2: Use AI to Research and Plan

In Summer Engine’s chat, ask the AI to:
  • “Use shell and tools to research my Unreal project at [path]. Analyze the structure, levels, and Blueprints. Create a migration plan.”
  • “Based on my Unreal project structure, what’s the best order to rebuild the core systems?”
  • “List the main levels and actors I need to recreate”
The AI can read your Unreal project files (Blueprints, level structure, asset references) and create a step-by-step plan.

Step 3: Rebuild with AI Assistance

1

Start with core systems

Rebuild your player, camera, and core mechanics first. Describe what you had: “Create a first-person controller with jump and crouch”
2

Recreate levels

Describe each level: “Build an outdoor environment with terrain, trees, and a building”
3

Import or regenerate assets

Use Summer Engine’s AI asset generation for placeholders, or import your existing art and audio

Project Size Matters

Project SizeDifficultyApproach
Fresh / smallEasyOften one-shot. Describe the game, AI rebuilds it
MediumModerateBreak into systems. Migrate level by level
LargePlanning requiredAI researches first, creates detailed plan. Migrate in phases. You already have assets. Focus on structure and logic
