Why do I need to re-cook textures after moving my project?

I let my computer compress textures overnight at home, which took many many hours at the highest settings. Thankfully after this, any updates I want to deploy to my iPad take less than 2 minutes. Perfect.

But when I copy my project directory over to my work computer, I need to re-compress every single texture again. My app is only 400 MB and the project is almost 4 GB, so there is obviously all the cooked content it could ever want.

This is a huge hassle and you can imagine how it would get in the way of development. I’ve experienced this in 4.7 and 4.8 if it matters.

Thank you for your report. We were not able to investigate this on the engine version you reported, but there have been many version changes to UE4 since this question was first posted.
