| 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. | This is caused by the IK foot placement system that relies on animation of the IK bones.

| For the running animation we'll create a duplicate of the Blend Space asset, then swap out the running animation. | For the running animation, create a duplicate of the Blend Space asset and replace the run forward animation in the Blend Samples section of the Asset Details panel. Then update the Walk / Run state graph in the animation blueprint to use the new blend space asset. |

| 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. | Note: The walk to run blending uses sync markers in the animation assets that indicate when each foot is on the ground.
