## Animation

### Tracks

Parameter ID: `USDIMPORTER_ANIMATION_TRS`

Activate this option if animations are to be imported. You can see what kind of animations can be imported here: [What kind of animations can the USD import/export handle?](https://help.maxon.net/c4d/en-us/Content/html/78533.html.md)

### Clean Tracks

Parameter ID: `USDIMPORTER_ANIMATION_CLEANTRACKS`

This option corresponds to the [Clean Tracks](https://help.maxon.net/c4d/en-us/Content/html/15460.html.md) command of the same name in the timeline. When importing, many adjacent keys with the same key values are reduced to the first and last of the identical keys.

### Skin

Parameter ID: `USDIMPORTER_ANIMATION_SKELETAL`

This setting is about loading "USD skeletons", which are imported into Cinema 4D as joint hierarchies with weightings and skin objects - i.e., the basis of a character animation.

If the option is activated, these are imported, otherwise they are omitted. **Tracks** and **Skin** should therefore both be activated if you want to import character animations - if **Tracks** are deactivated, only joints/skin objects are imported without any animation tracks.
