Template Project

We provide a ready-to-use UE 5.7 project with MetaHuman Optimizer pre-installed and the folder structure below already in place.

Download the template project (Dropbox link, placeholder)

Open it in UE 5.7, add your MetaHuman characters, and you're ready to start processing straight away. You don't need to modify your main game project at all.

Recommended Project Structure

When using MetaHuman Optimizer in a project, a consistent folder structure will keep your assets, exports, and scripts organised across multiple characters and workflow iterations.

Here is a structure that works well with the plugin's default paths and conventions:

TXT

YourProject/
├── Content/
│   └── MetaHumans/
│       ├── Creator/           # Keep your assembled characters here
│       │   ├── CharA/
│       │   └── CharB/
│       └── Optimized/         # Keep your optimized characters here
│           ├── Animation/     # AnimBP and other helper files
│           ├── FaceMeshes/    # Keep face meshes here
│           └── GroomBindings/ # Bindings are exported here
│
└── Plugins/
    └── MetaHumanOptimizer/    
        ├── Animation/         # AnimBP and other helper files
        ├── BlenderScripts/    # I/O & blenshape merging scripts
        └── Data/              # CSV files for reference

And on disk (outside of UE), a folder for OBJ exports:

TXT

D:\MyExports\             # Or wherever you prefer
├── CharA/                # Per character folders created automatically
│   ├── Neutral_LOD0.obj
│   ├── EyeBlinkLeft_LOD0.obj
│   ├── JawOpen_LOD0.obj
│   └── ... (52 pose files)
└── CharB/
    └── ...

Default Content Paths

The plugin uses these default Content Browser paths, which you can change in the UI:

Setting	Default path
Auto Assembler export folder	`/Game/MetaHumans/Creator`
ARKit animation sequence	`/MetaHumanOptimizer/Animation/AS_MH_ARKit_ROM`

The ARKit animation asset path is set automatically and you normally never need to change it. If it shows as missing, one of the required MetaHuman plugins is not enabled. See Requirements.

Blender Python Scripts Location

The Blender scripts are included with the plugin. Depending on your install method:

Engine install:

TXT

...\UE_5.7\Engine\Plugins\Marketplace\MetaHumanOptimizer\BlenderScripts\
├── MergeArkit.py        # Import OBJ poses as Blender shape keys
├── AddBlendshapes.py    # Add shape keys to an existing Blender mesh
├── FBX_Import.py        # Import preset for FBX files from UE
└── FBX_Export.py        # Export preset for FBX files to UE

Per-project install:

TXT

...\YourProject\Plugins\MetaHumanOptimizer\BlenderScripts\

Tip

If you plan to use the Blender workflow regularly, copying the PythonScripts folder somewhere stable on your disk (outside of any UE installation) makes them easier to find and version independently.
