Heya,

Theres a little issue with the world streaming needing time for the map to be reloaded back into the launched session.

When you start the memory test, it prompts to make a private upload, after it does this, it shows a map code, at this window don’t click to continue, until the map has fully reloaded back into the edit/play mode.

Waited for 5 minutes, map was fully loaded yet it’s still at 0%

4

Ouch…

At least you know its streaming/HLOD issues…

How long have you been using streaming with this project ?

5

Since the release on september 27th

6

Did you deleted any custom assets before your problem ?

7

Yeah i was making an update to my map, and 90% of the assets are custom so I deleted something for sure.

8

The HLOD layer may have old references stuck in it, check this thread…

Make sure you close live session if you decide to try replacing HLOD

I deleted and rebuilt my hlods and now i can’t even launch the session, it’s stuck at uploading project at 100%…

10

What is in your Output Log ?
Got any Red Lines ?

11

I cancelled the upload to check the output log and that’s how it looks

The cancel may have stopped the offending file from being shown, can you wait a bit longer and see if it throws out a name ?

What is the size of your Custom Content in the Project Size ?

13

I’ve waited for a long time, the logs just keep saying this. The project size is 18% (70MB) yet when i launch the session it says 587MB on the Uploading Project screen

I’ve deleted the HLODS for now and it works fine, guess I won’t be adding these to my map

15

I’ve just adding HLODS to another project that had streaming disabled before and it stops working as well, there is something wrong with my UEFN.

16

That is a shame…
The error messages I’ve seen before usually give some indication of whats going on, these ones give no pointers, other than being HLOD related only because it works without it.

A standard fix would be to find the offending asset and not included in the HLOD

I’ve found changing any Device, Landscape or Spline HLOD settings often causes HLOD failure.

I haven’t been using any custom assets so I’m unsure how to debug other than trial and error removing them from the HLOD and checking to see if they run.
Or if your map is mostly working well, take HLOD off everything and add it back only to whatever props are popping up out of thin air when you playtest your map.

Are you using any of the same custom assets on both ?

Maybe it could be something else, perhaps a UEFN bug related to the method your using for your bodycam visuals.

But workarounds and trying to find/sort out HLODs is nasty when all you want to do is create.
