In this section we'll cover how to use retargeted Mixamo characters and animtions with the Third Person Template.

We will assume you have created a project from the third person template, or have added the third person content pack to an existing project.

Simply replacing the animations in the Animation Blueprint for the UE5 Mannequin with retargeted animations will cause issues with the animation playback. This is caused by the IK foot placement system that relies on animation of the IK bones. These IK bones aren't present on Mixamo characters, thus there is no animation track for them in retargeted animations. This can be fixed with a simple change to the mannequin foot IK Control Rig to set the transform of the foot IK bones to match the corresponding foot bone.

1. Import a Mixamo character with the animations you want to use and retarget them to the UE5 Mannequin using the plugin. See our Getting Started documentation for more information on the retargeting process.

2. Create a duplicate of the Animtaion Blueprint Characters/Mannequins/Animations/ABP_Manny or ABP_Qunn. Then open the blueprint and replace the animations with the retargeted Mixamo animations.

In this example we'll replace the idle and running animations.

The idle animation is a simple swap.

For the running animation we'll create a duplicate of the Blend Space asset, then swap out the running animation.

Note: The walk to run blending uses sync markers in the animation assets that indicate when each foot is on the ground. This is used to match up the timing of the animations to make them blend together correctly. These markers can be added to you retargeted animations by right clicking in the timeline and selecting Add Sync Marker>Existing Sync Markers then choosing either the L or R marker to match with your animation.

3. Create a duplicate of the foot IK Control Rig asset Characters/Mannequins/Rigs/CR_Mannequin_BasicFootIK.

Then open the Control Rig graph and add nodes to the beginning of the graph to set the foot IK bones transform to match the corresponding foot bone.

4. Open the AnimGraph in the Animation Blueprint and edit the settings of the Control Rig node to use the modified Control Rig asset.

5. Duplicate the third person character blueprint ThirdPerson/Blueprints/BP_ThirdPersonCharacter.

Then edit the mesh component to use the modified Animation Blueprint.

6. Edit the third person game mode ThirdPerson/Blueprints/BP_ThirdPersonGameMode to use the modified character blueprint.

Now open the map ThirdPerson/Maps/ThirdPersonMap to test your changes. If you followed the steps correctly you should now have you Mixamo animations playing back correctly on the third person mannequin character.
