xhr.504 Error when trying to publish a map.

OK, that looks cool,
it does look like you have enough fog to not need HLODs

Are you getting any popups of buildings when they get into the loading range ?

If you are and need them to fade off into the distance a bit more, then you’ll need to build HLODs

If not, go ahead and start a Memory Calculation

Before you do a Memory Calculation it might be a good idea to do a Validate Project, access it via the menu in the 3 dots next to Launch Session, it will take a while maybe 10 minutes or so

If all is well Launch the Memory Calculation via the Project drop down menu.
