This is a simple demo mod that introduces a modified version of the tree feature that takes the normal tree configuration, but can be placed on almost every type of block. Allowable blocks are listed in a block tag, valid_ground_blocks.json, which can be edited to control what blocks the modified feature is placed on.
To demonstrate the modified tree feature, this mod includes an overworld with sponge-like "trees" added to the seafloor, a swamp biome bush that can grow in 1-2 block deep water, and a cave dimension with cave trees added, which can be accessed using the teleport command. The cave tree configured features are defined in json so that those interested in using datapacks can see how the modified tree feature is referenced.
