Okay! So if anyone else has the same issues as my further down the line here is what happened and how I solved it:
- UE4 wanted me to get Visual Studio 2017 in order to pack the game. I went and got the 2019-version. That was a mistake, I would later find out that you need the 2017 version in order to pack with FMOD(as far as I can tell).
- The game would not pack because I had a fmod-file with an “&”-character inside of the file name. Easy fix.
- The game still did not want to pack because some material with missing files in them. Removed those since I was not even using them.
- When I finally got a working package the game was missing all of the FMOD audio. The fix was to “validate FMOD” in the UE4 help Menu.
I am glad I am finally got this sorted, as someone that is just a few months in to making games and UE I have now learned that I need to take all warnings when compiling and building seriously if I want to be able to pack. Hope this is helpful to anyone else. Cheers!
