Nope it still doesn’t find the map package.
It logs something different because it detects a full path and goes through a different branch of code.
Can you go back to where it worked (loading actors), and print the full path of actors/classes after loading them from the pak ? This might help figuring out what’s wrong.
Also, can you post a dump of the pak contents with UnrealPak ?
edit: Also noticed something, as per this message
'../../../Photogrammetry/Content/Scans/RHK/' is not mounted to a valid Root Path yet
The /Game/ root path should already point to your main project’s content. Does that mean your main project is not called Photogrammetry? If you are trying to mount /Game/ to two different paths you are going to run into issues, one of either will be unreachable.
