Automatically generate a UE5 Mannequin-compatible skeleton for your humanoid characters. No manual bone placement.
Select one or more characters in the Content Browser, right-click, and choose Generate UE Skeleton (Free). The plugin detects the body and fingers and fits the 64 core bones of the UE5 Mannequin skeleton inside each character, then creates a new Skeletal Mesh next to the original.

Features
Automatic body and finger detection, using bundled neural models that run offline on your CPU.
One-click skeleton generation for characters in a T pose or an A pose.
Works on Static Meshes and Skeletal Meshes.
Batch processing: select several characters and run them all at once.
UE5 Mannequin-compatible: same bone names, hierarchy and bone axes, so Manny and Quinn animations retarget to the result.
Non-destructive: new assets are created and your original assets are never modified.
No setup: the UE5 Mannequin or Third Person content doesn't need to be in your project.
Good to know
The free version creates the 64 core bones only, with no twist or IK bones.
It doesn't calculate skin weights. Bind the skin afterwards, for example with the Skeletal Mesh Editor's Bind Skin tool. Skeletal meshes keep their existing weights on Mannequin-named bones.
Facing direction is detected automatically (±X or ±Y).
Requirements
Unreal Engine 5.8 on Windows 64-bit.
These Epic plugins, which ship with the engine and are enabled automatically: Mesh Modeling Toolset, Geometry Scripting and NNERuntimeORT.
