Infinite Characters · Plugin documentation

Plugin for Unreal Engine 5.

Generate custom MetaHumans from a brief or a photo, directly inside Unreal Engine 5.7.4. This page walks you through install, first generation, package contents and common issues.

v1.0-beta UE 5.7.4 Windows 10/11 Editor plugin

What it does

The plugin embeds ic.infinitepeople.ai as a Slate panel inside the editor. From there you can:

1. Create a character from a text brief or a reference photo
2. Watch the generation pipeline run live (~7 minutes end to end)
3. Install the finished MetaHuman with one click into /Game/InfiniteCharacters/<id>/
4. Browse the public character library and download finished characters straight from the plugin

Installation

From Fab

1. Install the plugin through Fab as usual
2. Restart Unreal Engine 5.7.4
3. Open the plugin from Window → Infinite Characters

Manual install

1. Download the ZIP from media.infinitepeople.ai/plugin/InfCharacters_v1.0_UE5.7.zip
2. Extract into YourProject/Plugins/InfCharacters/
3. Restart UE5 (it auto-compiles on first launch)
4. Confirm the plugin is enabled in Edit → Plugins (search "Infinite Characters")

Quick start

1. Open: Window → Infinite Characters
2. Sign in: click "Continue with Google" (a local browser will pop the OAuth flow on port 8080 — allow UnrealEditor.exe through Windows Firewall if prompted)
3. Create: write a brief and/or drop a reference photo, then press Bring to life
4. Wait: about 7 minutes — the progress panel shows the live pipeline state
5. Install: click Install in UE5 when the character is ready

Characters land in Content/InfiniteCharacters/<id>/, ready to drag into a level.

Package contents (per character)

Each generated character is delivered as a single ZIP (~120 MB) containing:

Requirements

• Unreal Engine 5.7.4 — strict requirement for the current beta
• Windows 10/11 (64-bit) — uses PowerShell for ZIP extraction; Mac/Linux on the roadmap, not available yet
• MetaHuman plugin enabled in your project (Edit → Plugins → MetaHuman)
• Active account on ic.infinitepeople.ai — free signup, no card needed
• Internet connection — generation runs on our infrastructure, no local GPU required

Pricing

The plugin itself is free. Character generations are billed through your account on ic.infinitepeople.ai:

Troubleshooting

Plugin doesn't appear in the Window menu

• Check Edit → Plugins, search "Infinite Characters", make sure it's enabled
• Restart UE5 if you just enabled it

Authentication fails or browser pop-up never returns

• Make sure port 8080 isn't blocked by Windows Firewall
• If Windows Firewall prompts, allow UnrealEditor.exe on both private and public networks
• Check the Output Log (Window → Developer Tools → Output Log) for the OAuth callback URL

Import fails after generation completes

• Verify disk space available (each character can take ~120 MB before import)
• Check the Output Log for the precise error
• Ensure PowerShell is available on your system (default on Windows 10/11)
• Common cause: the project folder is read-only or sync'd with OneDrive/Dropbox; move it to a local non-sync'd folder

The character looks off / artifacts on the face

• This is generative AI — variability is expected. Try a more specific brief or a higher-quality reference photo
• For tricky details (small features, ethnic markings, subtle expressions), plan a manual refinement pass in MetaHuman Creator afterwards — the plugin output is a fully native MetaHuman, editable like any other

For artists, by artists

This plugin is designed to accelerate the early phases of character work — the base modeling, the initial texturing, the rig setup — not to replace artistic judgement. The best results come from combining the AI's speed on the base pass with your expertise on the final 20% that defines the character.

• Touch up textures in Photoshop or Substance to perfect details
• Adjust proportions and features in MetaHuman Creator to match your vision
• Fine-tune materials, shaders and skin properties
• Add custom clothing, accessories, hairstyles that make the character truly yours

Generative AI — disclaimers

Infinite Characters creates original fictional characters inspired by the prompts and images you provide. It is not a digital cloning tool: outputs are artistic interpretations, not forensically-accurate likenesses. Same input may produce different output across generations.

You remain solely responsible for the rights to any reference photo you upload. The pipeline detects well-known faces and asks for appropriate consent before generation. For commercial use of characters inspired by licensed or copyrighted material, obtain permission from the rights holders.
