Hi @mikeweiss, thank you for the tutorial! I have a question regarding using pak files in the editor. I have a pak filled with animations that I am able to mount, load, and use in the editor, but I am running into crashes when closing the editor during the RemovePlatformFile function in PlatformFileManager. I’ve looked through source and the forums and seem to be finding some mixed messages regarding pak file usage in the editor so I was just wondering if you had any insight?
