Retargeting Animation in Unreal Engine: A Step-by-Step Guide

Introduction

In this tutorial, we will explore the process of retargeting animations in Unreal Engine. Specifically, we will focus on transferring animations from a standard character to the Unreal Engine mannequin. Retargeting can be a challenging task, especially when dealing with characters with different skeletons. However, by following the steps outlined below, you can efficiently retarget animations and ensure smooth transitions.

Setting Up the Project

To begin the retargeting process, follow these steps:

Creating a New Project

1. Launch Unreal Engine and open a new project.
2. Select the third-person template to create a new project. Name it accordingly.
3. Ensure that the Unreal Engine mannequin is available in the project.

Rigging the Character

1. Navigate to the character mesh and create a rig by selecting 'Create Rig.'
2. Apply the rig to all bones of the Unreal mannequin.
3. Save the rig and use the current pose for the character.

Exporting and Importing Animations

The next steps involve exporting and importing animations:

Exporting Animation from the Character

1. Save the animation from the character model using the export function.
2. Ensure to save the character in the T-pose for accurate retargeting.

Importing Animation to Unreal Engine

1. Create a new folder in Unreal Engine to import the character and animation.
2. Import the character model and animation, ensuring correct rotations.
3. Apply the bones to the character rig, considering any differences in bone structure.
4. Adjust any discrepancies in bones and save the changes.

Retargeting Animation

Once the setup is complete, proceed with the animation retargeting process:

Mapping Bones

1. Align the bones of the character model with the Unreal mannequin bones.
2. Address any differences in bone structure, such as spine or finger bones.
3. Save the bone mapping configuration for accurate retargeting.

Applying Animation

1. Import the animation data to Unreal Engine.
2. Retarget the animation by connecting the character model to the Unreal mannequin.
3. Verify the animation by playing it in the preview window.

Fine-Tuning the Animation

For further customization, follow these steps:

Editing Animation Details

1. Make adjustments to the animation to suit the character model.
2. Correct any discrepancies in hand or limb positions.
3. Use tools like the mirror tool to mirror animations accurately.

Reapplying Changes

1. Export the modified animation data.
2. Import the updated animation back to Unreal Engine.
3. Review the animation to ensure all changes are reflected accurately.

Conclusion

By following this comprehensive guide, you can successfully retarget animations from a standard character to the Unreal Engine mannequin. The process involves meticulous bone mapping, animation adjustments, and thorough testing to achieve seamless results. Experiment with different animations and fine-tune them to create engaging and dynamic characters in your Unreal Engine projects.
