## Cinemachine and Camera Errors
If by any chance,when importing the asset to Unity 6, you are getting these errors from the ThirdPersonFollowTarget script.
Please make sure you remove **Cinemachine2** from the Package manager, install **Cinemachine3**, and upgrade the prefabs here:
## The animal is not moving
You are making a custom animal, but when you try to move it, it does the animations, but won't move forward. Most of the time, the animations you are using are not RootMotion.
Check this [**Tutorial**](/animal-controller/how-to-ac/movement-no-rm-anims.md)**.**
***
## The animal is falling near the ground
If the animal starts to **fall** for no reason, it should be because the **Ground Layer** in the animal controller is set to Nothing, or the layer of the Game Objects considered ground is set to a different layer.
The Default value for the Ground Layer is *Default*. You must add your other ground Layers to the Animal **Ground Layer Mask**.
***
## States are not getting active or are \[Pending] (Missing Tag)
When the state does not get active, or the state goes to the **Pending** state, usually the reason is that The **Animation tag** is not properly set.
Make sure the Animation Tag matches your State :
Name of the State tag is the ID Name
This name must match on the Animation State Tag
{% hint style="warning" %}
The tags are **case-sensitive**. E.g. make sure you set **Locomotion**, instead of **locomotion**
{% endhint %}
***
## The Character slides on Slopes
If the character slides when it's on slopes, make sure the Main Collider is not touching the ground. The Animal Controller works with a floating Main Collider. Make sure the collider is set from the Hip to the Head
The Interaction with the ground is calculated using rays
***
## The character jitters when it moves
{% embed url="" %}
If the character jitters, ensure the Brain Camera is set to Fixed Update and the Animator Controller is set to Animate Physics.
