The strange thing is that this is totally new, and there doesn’t seem to be any reason for it. I’ve packaged the same project before on the same machine.
Not sure if it has anything to do with move from 5.0 to 5.1?
I have 8Gb RAM and GTX 1050i. I realise this is limited but it’s a failry simple project and had no problems before.
I’ve tried adjusting the paging file to provide more virtual memory (as much as 32GB).
At the same time, I’ve been having problems with baked lightmass not appearing in packaged projects. I can’t see how these problems are connected, unless I’ve made a change to my project settings when trying to fix issues.
