## Layer

### Track

Parameter ID: `TRACKFIELDLAYER_TRACK`

Drag and drop the animation track from the Timeline here. The values of this animation track will then be offset against the other levels of the Field list according to the following settings.

### Absolute Value

Parameter ID: `TRACKFIELDLAYER_ABS`

Activate this option if you want to prevent negative input values. Negative values will then be included in the calculation as 0.

If this option is activated, **Recalculate inputs** will never enter values less than 0.

### Type

Parameter ID: `TRACKFIELDLAYER_DERIVATIVE`

Define here which values of the animation track are to be used for the calculation. You can choose from the following:

- **Value**: The actual - usually interpolated - key value will be used here.
- **Speed**: The speed at which the value changes is included in the calculation.
- **Acceleration**: This makes the value change acceleration available to the calculation.

### Recalulate Inputs

Parameter ID: `TRACKFIELDLAYER_RECALC`

This button takes the work out of analyzing the animation track and finding the minimum and maximum values as the input range. Simply click on it and the corresponding values will be entered under **Lower In** or **Upper In**

### Input Min

Parameter ID: `TRACKFIELDLAYER_FROM_MIN` · Range: [-∞..+∞]

### Input Max

Parameter ID: `TRACKFIELDLAYER_FROM_MAX` · Range: [-∞..+∞]

### Output Min

Parameter ID: `TRACKFIELDLAYER_TO_MIN` · Range: [-∞..+∞]

### Ouput Max

Parameter ID: `TRACKFIELDLAYER_TO_MAX` · Range: [-∞..+∞]

These 4 values are used to define the value input range and the value output range. The former is transferred proportionally to the value output range (see also [level control](https://help.maxon.net/c4d/en-us/Content/html/FLRANGEMAP-FLBASE.html.md)).

### Offset

Parameter ID: `TRACKFIELDLAYER_OFFSET` · Range: [-∞..+∞]

This can be used to define a time offset for the animation track. Enter the value in seconds. Negative values are of course possible here to enable earlier times.

You can use [subfields](https://help.maxon.net/c4d/en-us/Content/html/58091.html.md) for the **Offset**.
