Summary

After building HLODS the map can not be uploaded. Deleting HLODS fixes the issue but HLODs are needed in my map to reduce memory impact and reduce draw distance

Screenshot of the error message which is pretty unnclear.

Also this has happened to some other people before:

Already tried rebuilding multiple times, tried removing custom meshes from HLODs and tried validating all assets / resaving all assets but without success. My current suspicion is that it might have something todo with custom meshes in foliage mode

Yeah this is quite a big problem especially for larger maps, can also verify this is happening for me!

Having the same issue. Spent almost two months on this map, and I cant continue with it. Really hoping all these hours did not go to waste.
