Large Hitbox Set
The Large Hitbox mode makes the Structure Void's hitbox the size of a full block. So if you want to place blocks on Structure Void, this mode may make it easier for you.
3 options as of 1.19.2+!
You can find the keybinds for this mod in the keybind menu! Previously to 1.19.2, the keybinds were in the Misc categeory. Now they are in this mod's specific category.
No Hitbox Set
The No Hitbox mode will let you treat Structure Void blocks as air blocks so you can mine and place blocks through them without them being in the way!
