How to set up a 3D model for animation in Unity

Importing Your 3D Model

To import your model, follow these steps:

1. Open Unity and create a new project or open an existing one.
2. Go to Assets > Import Package > Custom Package.

   

3. Navigate to the folder where your 3D model is saved and select it.
4. Click on Import and wait for the model to be imported into Unity.
5. Once the import is complete, you can drag and drop the model into the Scene view.
   

   Rigging Your Model for Movement

   Now that your model is imported, it’s time to rig it for movement. Rigging is the process of creating a skeleton or control points within the model that will allow it to move and interact with other objects in the scene. To rig your model, follow these steps:

6. Select your 3D model in the Hierarchy view.
7. Go to Animation > Rigging Tools > Create Rig.
8. In the Rig window, click on Add Bone and give it a name.
9. Repeat step 3 for each joint in your model.
10. Once you’ve added all the bones, go back to the Animation window and click on Create Animation.
11. Give your animation a name and click on Create.
12. In the Animation window, click on Sources and select the animator controller you just created.
13. Now you can add keyframes to your animation by dragging and dropping them onto the bones in your model.
    

    Adding Animations

    With your 3D model rigged for movement, it’s time to add some animations. Animations are a series of keyframes that define how an object moves over time. To add an animation to your model, follow these steps:

14. Go back to the Animation window and click on Create > Clip.
15. Give your animation a name and select the animator controller you created in step 7 of the rigging process.
16. In the clip window, click on Add > Keyframe and give it a name.
17. Now you can add keyframes to your animation by dragging and dropping them onto the bones in your model at different points in time.
18. Once you’ve added all the keyframes, go back to the Animation window and select your animation clip.
19. Click on the Play button to preview your animation.
    

    Exporting Your Animation

    Once you’re happy with your animation, it’s time to export it for use in other projects or platforms. To export your animation, follow these steps:

20. Go back to the Animation window and select your animation clip.
21. Click on Export > Animation.
22. In the export window, select the format you want to export the animation in (e.g., .mp4, .avi).
23. Choose a location to save the exported file and give it a name.
24. Click on Export to save the animation file.
