Workshop Script and Location Data: What does "Parent Worldspace" do?

[Zorkaz]

When you create a settlement you also have to create Location Data.

 

In the location data you set your parent worldspace to CommonwealthLocation in most cases.

 

But is it necessary and do you need to set another worldspace, when creating a custom world?

 

Any experience would be helpful

It's mainly for indoor settlements to enable bunch of functionality, like synced (to outdoor region) weather.

I don't think you need to set it for a custom worldspace. Doesn't make sense, really and Nukaworld doesn't seem to have a Parent for it's Worldspace either.
