I took suggestions to add anti x-ray feature so i added it.


Just add some new sections in world settings of any treasure(settings defined to each world you want to protect and can be different to each world and treasure):

Hidden parameter defines to hide treasure from x-ray or not
Material - what block type will be instead of chest
AppearAfter - distance after wich chest will appear as chest block
If distance (after checking distance to chest or, in other words after LMC with HuntTool) to chest will be less then AppearAfter distance, chest will appear as chest block. So players with x-ray lose advantages on little distances to chest.
