## PartialOffloadAction

### Introduced

v4.0

### Description

Partially offloads one or many fcurve action sources for a given range of frames. The action source needs to have external storage in order to be able to execute this command.
Before offloading an action source, if the action is dirty it is exported. Once offloaded or partially offloaded, an action source never exports the data again. When an action source is partially offloaded, the Status parameter of the source becomes siActionStatusPartiallyLoaded (see siAssetStatus).
Note: This applies only to the FCurve action sources.

### Scripting Syntax

    PartialOffloadAction( [InputObjs], StartFrame, EndFrame, [Remember] );

### Parameters

Parameter | Type | Description
--- | --- | ---
InputObjs | String | List of action sources to process. Default Value: Current selection
StartFrame | Integer | The frame to start offloading the fcurve keys. If smaller than the AnimStart parameter on the action, the AnimStart value is used instead.
EndFrame | Integer | The frame to end offloading the fcurve keys. If greater than the AnimEnd parameter on the action, the AnimEnd value is used instead.
Remember | Boolean | If true, the range of frames is appended to the parameter OffloadedRanges of the action, so when the scene is reloaded the partial offload will be processed. Otherwise, it is only temporarily offloaded. Default Value: False
