You can hook into supported plugins by adding them to the hooks.yml file. For example:
In EpicBuckets you have different genbuckets you can use. These can be found in the EpicBuckets shop. These are the following types of EpicBuckets.
Vertical Buckets: These can only be used on the top and bottom of a block. Placing the bucket on the bottom of a block generates the blocks downwards; placing the bucket on the top generates the blocks on top.
Horizontal Buckets: These can only be used on the side of a block. The blocks will be generated in the direction of the side where the bucket is placed.
