Worldgen Filler

Filler is an object that defines blocks contained in worldgen definition and their types.

General structure of filler would be:

"filler": {
    "type": "filler type",
    additional filler-specific arguments
}

Available Filler Types:

Simple

type: "simple"

Entire definition is filled with same block supplier, distance from vein center doesn't matter. Additional Arguments: "value" - specifies block supplier used for entire vein generation.

Ignore Bedrock

type: "ignore_bedrock"

The vein will be generated as in a Simple block filler, but will not replace bedrock with bedrock ore variants and instead leave the bedrock as is, generating around it. This is mostly used for Material blobs, such as Marble, Basalt, etc. However, this can be used to ensure that bedrock ore variants are not generated, as there is currently no way of mining them.
