Welcome to the Dreamcraft Network's Modified Structure Block mod! This mod works on modifying the hard limits of the structure block, so you can save larger structures!

How does this work:

Well this mod works by scanning the larger selected area, and then it saves the structure by chunk, creating a struture nbt index, as well as all the structure chunk nbt files. Then when loading, just use the original name of the saved structure, and placing works just like so! Keep in mind you do NOT need to use any of the chunk parts that were saved when trying to place your structure. For instance "Castle.nbt" is the original structure name, but it can save a Castle_Index.nbt, Castle_000.nbt, Castle_001.nbt and so fourth, just use Castle as the name of the structure your trying to place. that will then load your Castle Index and place the files exactly how the structure block works!


For mod creators:

If you plan on adding this mod to modpacks to place larger structures, it is a requirement that this mod is installed or the structures will fail to place. My code does NOT work like Mojang's or Neoforge's code, thus meaning if you create a structure mod, you should use the example classes bundled with the mod jar, (will be available on my github or website in the future)
