Migrate from Unity to Summer Engine

You can migrate your Unity 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 Unity Project

1

Document your project

Have a clear picture of your scenes, 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 Unity project at [path]. Analyze the structure, scenes, and scripts. Create a migration plan.”
  • “Based on my Unity project structure, what’s the best order to rebuild the core systems?”
  • “List the main scenes and prefabs I need to recreate”
The AI can read your Unity project files (C# scripts, scene 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 3D character controller like my Unity Rigidbody setup”
2

Recreate scenes

Describe each scene: “Build a level with a ground plane, obstacles, and spawn points”
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 scene by scene
LargePlanning requiredAI researches first, creates detailed plan. Migrate in phases
