I was able to cook/package for Win64 in about 30 minutes (I develop in a Win64 environment). Packaging from the same machine for Linux took ~15 hours. Packaging for Mac has been going for 10 hours already.
Is it possible to reduce the content cook time for Linux and Mac? I can see that certain textures and levels take 1-2 hours; is it known why this happens? Is there any way to use the cooked content for a Windows build in the Linux or Mac builds?
I’m currently packaging through the editor on Windows and the command line on Mac. Happy to provide an archive of my project if you need a repro case.
UPDATE: I killed the in-editor Mac packaging process and ran it from the command line and it took about 15 minutes.
