Some UMaps from Chapter 5 Season 3 are not converted when you select and give an error, mostly it's the ones with the POIs in them.

I will also include one or two UMaps for you to test

2QGNO52XD97ZZGVB3BHHMVGN8.json
5HRG0S8E52BPP3LNJMBQHCSQE.json

9Q4V4FDWD6SGZJ7CSPD4BI468.json
591GRPNWCJ9WVOC11TSXQWY1K.json

And here is the error code that is output when converting

So in some umap files they use other levels (such as a poi using buildings) and since you can't access the game files on a website I was thinking you could add a dialog that opens when you press the convert button that asks for the other levels in the uploaded umap. Since you can't really use levels if you want to use it in UEFN I was also thinking you could use a FortPlaysetRoot (what prefabs use) to sort of separate the levels and position them correctly. One last thing you could do is instead of putting things in a folder you could use the FortPlaysetRoot so you are able to move it around without messing things like walls or floors up.

Better styling of the page
I am not quite happy with the styling for now, thats why i am proposing some changes.

Describe the solution you'd like

• Make the UX smoother, more css transitions, for a better feeling when navigating

• Dark Mode feature

• Maybe themes which will be saved using javascripts local data(?)

I would try to implement the changes and open a pull request as soon as i am ready :)

Add extra Info block in the help section about how you import converted maps into uefn (because layer 8 problem).
Something like:

"How do I get a converted map into UEFN?"
"You copy the content of the converted .txt and then in UEFN paste it (its recommended to do this in an empty level)"

Description
When the script converts the Json file into a pasteable .txt file, instead of changing a BP's mirrored function to "True", it simply sets the scale to -1. This would be fine, however it causes doors to open in strange ways. The fix to this in UEFN is just to enable mirrored, which causes them to open normally again.

To Reproduce

1. Go to fmodel and find a umap you wish to convert.
2. Save the json and put it in the converter.
3. Go back to the Fmodel umap and search up "Mirrored"
4. Find the display name of the actor, it will be nearby the "Mirrored" thing, next to "Name", copy the display name.
5. Go to the converted .txt file and search that name, you'll find that there is no "Mirrored: True" section, only scale -1.
6. Bonus, find a door with the scale of -1, (Not mirrored) go ingame and open the door, and you'll see how it opens weird. Then open a door that has "Mirrored" enabled, you will see it opens normally.

Expected behavior
At first I thought it was an Epic issue, as they have sometimes set the scale to -1 instead of mirroring, however I found out that the script simply doesn't have anything to enable "Mirror", I expected it to do that when converting.

Screenshots

^ ^ Here are two screenshots of the same actor, one in the original UMAP Json showing Mirrored: True, and another in the converted script txt.
