The title sais it all. I dont know if there is already such an option and i havent found it yet, but if there isnt, there should be an option that stops two objects from spawning too close.
For example: You have 4 BO3 Objects
Object1_not_near: Object2/(radius blocks)
Well sure you can control this with rarity and frequency, but come on guys... there is a chance and my objects are spawning inside each other.
(is there any pro-tip how to avoid that: my objects are made from the same block that they are allowed to spawn on)
Imagine a Dirt House allowed to spawn on Dirt, so more Dirt Houses are spawned on top of each other
