This example demonstrates how to achieve multi-layer animation blending in the Galacean editor. Through simple steps, you will learn how to blend multiple animations for a model. If this is your first time using the animation editor, it is recommended to read the previous documents:

1. Play Animation in Model

2. Reuse Animation

3. Animation Transition

0. Preparation

1. Before starting, we need a model with animations, and it should contain an animation suitable for blending. If you don't have a model, you can download the model here. Then drag it into the scene.

2. We need an edited AnimatorController. Please refer to: Edit AnimatorController.

1. Add an AnimatorControllerLayer

To blend animations, we need to add an AnimatorControllerLayer in the AnimatorController. When the Animator component runs, all Animation Layers will run together, and multiple Animation Layers achieve animation blending through different weights. For a detailed introduction to AnimatorControllerLayer, please refer to the AnimatorControllerLayer document.

Click + in the Layers panel to add an AnimatorControllerLayer

2. Edit AnimatorControllerLayer

Add an AnimatorState (if you don't know how to add it, please refer to: Play Animation in Model), bind the "shakeHead" AnimationClip in the model, and connect it from entry to this AnimatorState. You can adjust the transition time from entry to this AnimatorState as needed.

Edit and bind this AnimatorController to the model.

3. Adjust AnimatorControllerLayer Weight

The default blending mode of the newly added AnimatorControllerLayer is Override. Let's preview the effect first.

We can see that the AnimatorState added in the Base animation layer are all invalid because the blending mode is Override, which will override all the Animation Layers below it. We can adjust the weight of Layer1 to see the impact of the weight.

We can see that as the weight decreases, the influence of Layer1 on the animation becomes smaller, while the influence of Base on the animation becomes larger.

4. Adjust Blending Mode

In this example, we do not want the weight of Layer1 to affect the Base animation layer, so we change the blending mode of Layer1 to Additive.

In this way, the animation of Layer1 will be superimposed on the Base animation layer, and its weight modification will only affect itself without affecting the animation of the Base layer. To better observe the effect of Additive, we delete the transition from run to exit in the Base layer.
