Step 1: Download Mixamo Animation and Character
Go to Mixamo.com and select the character and animation you want.
In the Download Settings, choose FBX for Unreal Engine or FBX format.
Enable With Skin for character models or Without Skin if you only want the animation.
Download the file to your computer.
Step 2: Use Mixamo Converter Tool
To enable root motion, you’ll need to use a Mixamo Converter tool, such as Autodesk Maya’s Mixamo Rigging Tool or Blender’s Mixamo Add-on. You can also use plugins like the UE5 Mixamo Animation Retargeting Plugin for an easier solution.
If using Blender:
Import the FBX into Blender.
Apply root bone adjustments by adjusting the armature or using a Mixamo add-on for Blender that lets you add root bones to Mixamo animations.
Once done, export the modified animation as an FBX.
Step 3: Import to Unreal Engine 5
Open your Unreal Engine 5 project.
Go to Content Browser, right-click, and choose Import to bring in your Mixamo FBX file.
In the import options:
Enable Import Animations.
Make sure Import Mesh is unchecked if you’re only importing animations.
Click Import.
Step 4: Enable Root Motion in Unreal Engine
Go to the Animation Sequence you imported and open it in Unreal Engine.
In the Details panel on the right, scroll down to Root Motion.
Enable Root Motion by selecting Enable Root Motion and ensure Force Root Lock is on.
Set the Root Motion Mode to Root Motion from Everything if needed for full control in Unreal.
Step 5: Test and Adjust
Open the animation in Persona Animation Editor and check if the root motion is working properly by previewing the animation.
You can use root motion in Animation Blueprints or Montages for precise in-game movement.
Step 6: Use Root Motion in Gameplay
To use root motion in gameplay, go to your Animation Blueprint or character movement logic.
Set the movement logic to Root Motion Only under Character Movement for movement-based actions (e.g., attacks, dodges).
