There was a lot of activity while I was gone! I’m reading through and this caught my eye:
Error: DoesPackageExist: DoesPackageExist FAILED: ‘/Game/2nd characater textues/Textures/Z1_Rough_AO_Clean_4k’ is not a standard unreal filename or a long path name
The problem here is that “2nd characater textues” has spaces in the folder name. Spaces aren’t allowed in file/folder names inside of your project’s content structure. Removing any spaces that are present should be able to help with the errors related to this.
Edit: This also goes for the project’s folder name “demo finale”. Please remove the space from that as well.
