Model stored in [VoxelLibrary] and used by [VoxelMesherBlocky]. Represents a model to be used for voxels of a specific TYPE value. Such models must be contained within a [VoxelLibrary] to be used with [VoxelTerrain] or directly with a [VoxelMesherBlocky]. Some other various properties also exist to make it easier to implement games based on this technique (such as Minecraft). ID of the material that will be used. It corresponds to the index of materials found on [VoxelTerrain]. If enabled, voxels having this ID in the TYPE channel will be used by [method VoxelToolTerrain.run_blocky_random_tick]. Name that can be used for convenience, when looking up a specific [Voxel] from [VoxelLibrary]. Don't produce any geometry. The voxel will be invisible. Use the shape of a generated cube. It is useful for testing and quick configuration. Use the mesh specified in the [member mesh] property. This is the most versatile way to create shapes. How many geometry modes there are.
