How to Use Mixamo Animations in Unity for Custom 3D Models

In this blog post, we will explore the process of integrating Mixamo animations into Unity for custom 3D models. Mixamo, an Adobe service, offers a wide range of free animations and characters that can be seamlessly utilized in various projects, including games. Whether you are working on a personal game project or a professional endeavor, Mixamo provides a convenient resource for animations and models. Let's delve into the steps involved in incorporating Mixamo animations for custom models in Unity.

Preparing the Model in Blender for Mixamo Animation

Before diving into the integration of Mixamo animations in Unity, it is crucial to prepare your model properly. Here are the essential steps to follow:

Select an animation from Mixamo, such as the "Idle" animation, and download it in FBX format without skin.
Import the downloaded file into Blender and adjust the position of the skeleton to ensure it aligns correctly with your model.
Make necessary adjustments to the armature and spine to match the proportions of your model.
Check the rotation of your model and make corrections if it is facing the wrong direction.
Parent the model to the armature in Blender by selecting both objects and applying the armature with automatic weights.
Verify that the animation runs smoothly within Blender to ensure the setup is correct.

Exporting the Model to Unity

Once you have prepared your model in Blender, the next step is to export it to Unity for further animation integration:

Export the model from Blender in FBX format, ensuring to include the armature.
Import the FBX file into Unity, making sure to select only the necessary objects to avoid any misalignments.
Verify that the model appears correctly in the Unity scene, ready for animation attachment.

Adding Mixamo Animations to the Custom Model in Unity

Now that your custom model is imported into Unity, it's time to incorporate Mixamo animations:

Choose the desired animation from Mixamo, such as "Dance," and download it without skin.
Change the rig of your model to humanoid from generic to enable seamless animation application.
Remove any existing animation from the model and drag the new Mixamo animation onto the model's body.
Adjust the animation controller settings as needed to ensure smooth playback.
Test the animation within Unity to confirm that it integrates properly with your custom model.

Conclusion

Integrating Mixamo animations into Unity for custom 3D models opens up a world of creative possibilities for game developers and designers. By following the steps outlined in this blog post, you can enhance your game projects with high-quality animations seamlessly.
