I appreciate the thorough information.  Thank you

[Is this a possible world?]

Good afternoon;

 

I've got an extremely ambitious idea and am wondering if it is dead in the water.

 

Decent into hell, where instead of a traditional world, different biomes are stacked one atop another.  I suspect this will end up several thousand blocks high. 

 

Can it load chunks within a certain height?

Could it reference elevation for loot/game stage?

Is a vertical only vehicle ie elevator possible?

 

Thanks!
