Firstly, before you check this mod out, please remember it was never meant to be for public release. I made it so I could copy large structures that include modded blocks, so I could use them in other mods. Therefore, as this was never meant to be public, it isnt exactly the most optimized. There are still quite a few bugs and glitches, but i dont intend to fix any of them (unless it renders the mod unusable). Also please note that the size and relative position for the structure blocks is the same through out all of them.
HOW TO USE IT
This is what you have to remember. You cant use it like a normal structure block, using the GUI. The GUI is still there but only for saving and changing if entities are loaded in with it and stuff like that To change the size and the relative position, you have to use a command.
The command syntax is /st <pos:size> <axis> <value> OR /st <pos:size> <x> <y> <z>. (eg /st pos x 15 will set the x axis for the position to 15. /st size 14 26 61 will set the size of the blocks to x:14 y:26 z:61). This will apply those settings to all the custom Structure Blocks, so all of the Custom Structure blocks will update
