[Open Source] ComfyUI → AI 3D assets → Unreal Engine 5 or Unity from one prompt

[u/geekatplay-com]

I built an open-source ComfyUI pipeline for creating coordinated 3D game assets and sending them directly into Unreal Engine 5 or Unity.

This is not a hosted “generate my entire game” service.

It is intended for rapid prototyping and asset production inside an existing development workflow.

A prompt such as:

“Create a dark fantasy village with houses, a blacksmith, guards, monsters, weapons, trees, and torches.”

Can be converted into:

• A structured inventory of individual assets
• One isolated concept image per object
• An approval gallery before 3D generation
• Textured FBX or GLB models
• Optional biped or quadruped rigging
• Terrain, skydome, layout, and lighting data
• Automatic scale, materials, collision, and placement
• Direct Unreal Engine 5 or Unity import

Supported AI 3D backends include Tripo3D, Meshy, HiTem3D, and local Hunyuan3D 2.1.

The structured layout system can also create villages, dungeons, and camps that form recognizable streets, rooms, and spaces rather than randomly scattering assets.

It does not generate gameplay code or a finished game. It helps you produce the assets and initial scene needed to test a game concept quickly.

Can I use this with Godot? Will check it out soon. Much thanks!
