# Basic functionnalities

Here is a list of some functions you should know about. (all of these can be called in Blueprints or c++)

```
AddSkeletalMeshToStacker
```

Adds the component to the stack, this should be done on initialization or as soon as possible.

```
UpdateMorphTarget
```

Call this function instead on the Unreal base one in order to update a morph target, this only works when the skeleton is referenced in the component.

```
ClearMeshMorphTargetPriority
```

Call this function when a morph target is not in use anymore, be sure to call this function to free the priority slot.\
(there is multiple variants of this function to clear the data at diffrent levels)
