# Chunkload

Make your recipe chunkload an area around the machine.

The chunkload requirement can be used to make the machine chunkload an area around it.

Unlike the [Chunkload machine component](/custom-machinery-1.19/creating-custom-machines/machine-components/chunkload-component.md), this requirement will chunkload the area only while the recipe is processing.

If the recipe containing this requirement stop processing (because some other requirement aren't valid for example) the chunkload will stop too.

The type of chunkload requirement is : `"custommachinery:chunkload"`.

### Properties

The button requirement only has 1 mandatory property and 1 optional property.

#### Mandatory properties

```json
"type": "custommachinery:chunkload" //Mandatory to define a chunkload requirement.
```

#### Optional property
