Additional Notes

My prefabs contain meshes that were imported from Fortnite Porting, however they’re available in UEFN as well so shouldn’t violate rules. I mention this because I was told by another creator that this error is caused by flagged or corrupted assets.

Haven’t been able to work on my project for 2 days smh…so hopefully this get seen!

Has anyone at Epic seen this? In the meantime I removed all scene graph prefabs to about 260 and I can push changes, but any more I get the same error. Is there a limit I should know about?

Check your PC’s virtual memory (advanced PC settings), if you can get more than a 64Gb paging file, it may help, mines 160Gb on a separate hard drive

Epic staff rarely look in the forums, but if you get more than 3 votes on a post it goes into a queue.

There are limits on everything, but 260 seems a bit low for making a decent island, hopefully cranking up your Virtual Memory helps,
