A focused utility for the MetaHuman-to-Manny pipeline in Blender, updated in version 1.3.0 with IK bone generation.
MetahumanToManny is a Blender 4.2+ add-on that converts and binds MetaHuman skeletal meshes to the UE5 Manny skeleton. A typical run starts in Unreal: export the MetaHuman meshes to Manny, import them into Blender, select one LOD mesh, then Shift-select the armature and click Convert Skeleton To Manny. The add-on processes the remaining LODs in the same run.
Convert Skeleton To Manny handles the cleanup work together, running face bone weight cleanup, vertex-group cleanup, and seam fixes, then removing every armature bone not in its keep list. The Manual Steps section exposes each stage on its own, covering face cleanup, vertex-group fixes, seam repair, LOD hierarchy setup, and binding to Manny. Generate IK Bones adds the UE5 Manny IK and auxiliary bones to the selected armature.
Version 1.3.0 added the IK bones helper. The add-on works with Blender 4.2 LTS and newer, is released under the GNU General Public License v3.0 or later, and requires no special permissions. A tutorial video and documentation are available on the developer's page.
MetahumanToManny is best for blender artists converting MetaHuman characters to the UE5 Manny skeleton for use in Unreal Engine.
MetahumanToManny is completely free to download and use.
MetahumanToManny requires Blender 4.2.0 or newer, and the developer lists it as compatible with Blender 4.2 LTS and newer. Version 1.3.0 was published in November 2025. If you are running an older Blender build, you will need to upgrade before installing, since 4.2 is the stated minimum requirement. Once installed, the panel appears in the 3D Viewport sidebar (press N) under the MetahumanToManny tab, where the Quick Convert and Manual Steps sections live.
MetahumanToManny installs like other Blender extensions. Download the add-on zip, then in Blender open Edit → Preferences → Get Extensions, click the menu at the top right, choose Install from Disk, and pick the zip. From the marketplace you can also drag and drop the file into Blender. After installation, find the panel under 3D Viewport → Sidebar (N) → MetahumanToManny tab, which holds both the Quick Convert buttons and the collapsed Manual Steps.
MetahumanToManny is listed as free here, and it is released under the GNU General Public License v3.0 or later. The extension requires no special permissions. Because it is distributed under the GPL, you are free to use, study, and modify the add-on within the terms of that license. For current licensing details, the source code, or to report issues, check the developer's GitHub page linked from this listing.
MetahumanToManny's Generate IK Bones operator adds the UE5 Manny IK and auxiliary bones to the selected armature: ik_foot_root, ik_foot_l/r, ik_hand_root, ik_hand_gun, ik_hand_l/r, interaction, and center_of_mass. These bones are non-deforming and rebuild if you run the operator again. They also work on skeletons that have no root bone. The button sits in the Quick Convert section alongside Convert Skeleton To Manny, and it was introduced in version 1.3.0.
MetahumanToManny centers on its Quick Convert section. First export the MetaHuman skeletal meshes to Manny from Unreal and import them into Blender. Select one LOD mesh, Shift-select the armature, then click Convert Skeleton To Manny; the add-on processes the remaining LODs in the same run. Optionally click Generate IK Bones. Then run Setup LOD Hierarchy from Manual Steps, select every mesh plus the LOD empty, Shift-select the armature, and export.
