Well, it is a pre release right now, so you will not have that much.
Currently, the features are:
-Structure: Yacht, generated on oceans, you will find 1 in 20 chunks. It's made of Quartz. On it you will find Gold Blocks, Iron Blocks, a Diamond Block and some ores.
-Structure: Sword, big sword, containing a block which will give you a very good sword when molten.
-Structure: Shovel, a big shovel, containing a block which will give you a very good sword when molten.
-Structure: Axe, the same as the sword and shovel, just with an axe-block.
-Structure: Pickaxe, the same as the sword and shovel, just with a pickaxe-block.
-Item: Helper List, an Item which tells you about people who gave me structures for the mod.
-Item: Structure Spawner, spawns any structure you want.
-Structure: Bow, a big bow, giving you a good bow when molten (Bow Block)
Well, that's it, but I will do an update with a few more structures pretty soon!
Yes, I use schematic for input but code EVERY SINGLE BLOCK with help of a tool... @HarryThomas70 Sure I need structures, maybe you can send me a screenshot of a structure you made? Also, the structures can not be out in a folder and be generated, they have to be coded into the mod (I do not know any other way). As the helper list was a bit buggy, I am going to remake it and put your name on it when you made a structure :D. Just build anything you want, if I like it I will put it in
