SECTR import/export and GUI problems

[Fulip]

Hi, I have problems with SECTR:

1. When I use Export All Sectors function in SECTR Stream window, I get those exceptions, and Unity get stuck at Importing Assets loading bar.
I can only export sectors one by one using Export button. Import All button work's fine. 

GUI Error: Invalid GUILayout state in SECTR_StreamWindow view. Verify that all layout Begin/End calls match

2. I can't find option to import single sector, there is no Import (single) button in SECTR Stream window. 

I'm using Unity 2022.3.3f1 with URP.

I want to add that Import All button does not import all sectors in one click, I need to use it twice. 

[Fulip]

I think that the source of this issue is sector nesting. I was following documentation, and read in the part about:
Streaming in Layers / Nested Sectors

While it might be enough most of the time to stream Sectors that are nicely aligned with each other, it can also be useful to have Sectors inside of other Sectors.

And this is what I think causes my problem. (tested on blanc project) When I put a sector in to another sector, those errors occurs. How should correct nesting look like?

[Bryan]

You wouldnt be able to overlap a sector, which is probably causing the issue as you stated. 
A nested sector would be an environmental change sector of the same tile. 
An example would be Firewatch. 
The original sector looks all clean, however, eventually that same tile can be used as a dirty or destroyed tile just as a different sector.

Thanks, for the answer. After sorting that out, I still have problem with SECTR Stream window, and lack of Import and Revert buttons on the right of the sectors names.

[Fulip]

Okay, I found a solution. It turns out that the asset was having some kind of problem with the scene folder i think. It was creating many empty chunks folders (like chunks, chunks01...chunks53?), and scene named folders (and it was connected to the missing Import, Revert buttons). When I copied the scene to a new folder, it started working fine. I don't know the exact reason for this, there was no special characters in folder names etc.

Ah thank you for the info and glad it is sorted.
