consecutive is one of the feature
by CoFH World. It loops through a list of features,
providing the next feature in the list each time a feature is generated. Note
that the list is looped through separately per chunk; if one feature is
generated per chunk, only one feature in the list will be generated.
When using this feature type, the following value must be added to the feature type configuration.
||Array of feature type configurations and/or arrays of feature type configurations||-||The features to generate consecutively. Each item in the array is either a feature type configuration or an array of them. When specified as an array, a feature type configuration is selected randomly each time the feature is generated.|
