Open Standard Assets in the Package Manager and import it into your project.

Change GUIText to UnityEngine.UI.Text to fix the error.

Add the Third Person User Control to the 3D character as shown in the following image. Then, the Capsule Collider and Third Person Character will be added automatically.

Click on Edit Collider, and change the size of the Capsule Collider so that it matches the shape of the character.

Apply the leadingPersonAnimatorController to the Animation's Controller.

Now that you've done all this, let's run it and check it out! We have confirmed that the character moves in response to keyboard input.

Make the camera follow the character's movements.

Finally, change the main camera so that it follows the character.

Use the MMultipurposeCameraRig in the Camera prefabs of Standard Assets. Deactivate the main camera that exists by default and change the z-axis value of the prefab's main camera to move the camera closer to the character.

Apply a 3D character to the AutoCam target in MultipurposeCameraRig. All work is now complete.

Finally, I was able to run it and confirm that the camera follows the character.

With Vroid Studio, it is relatively easy to incorporate your favorite characters into your game development. I hope it will be useful to you in your game development.

Easily create your own unique character and incorporate it into your game!
