Performant-friendly Clone?

Hi - Bare with me on this;

I’m working with @EgoMoose Portal Module & I’m looking for a way to create a performant-friendly replica of the Overworld(s) dependant on the Players location…

So far, I’ve experimented with using OverlapParams which haven’t given the desired results ((Due to the filtering of the Tables in order to get Parts & determine whether they’re to be rendered, this causes performance issues and a increase in pings.))

I’ve also attempted to only render the Parts infront of any given Portal as behind aren’t necessarily required however I have the same issue – I’m assuming it’s due to the constant requirements and speed of tables as when I remove the requirement of the table overall, it’s fine.

Does anyone have any suggestions? – I’ve seen other games do this fine.
