load a level pak file(A-Level.pak) into a new project B, how to keep the default gamemode in project B?

we pack a level in project A into file named A_Level.pak, this level has no gamemode in default. Then we hot-reload this pak file in a unrelated project B in runtime, but there’s a problem:

in project B, our step is:

  1. FPakPlatformFile::Mount(A_level.path);
  2. using RegisterMountPoint make A register in the path “/Game”

after step 2), we found the default content path in project B is invalid, and something error occurs when loading the A_Level, error info like this:

LogLinker: Warning: Failed to load ‘/Game/BSEditor/Blueprints/GameMode/BP_BSEditorGameMode’: Can’t find file.
LogLinker: Warning: Failed to load ‘/Game/BSEditor/Blueprints/GameMode/BP_BSEditorGameMode’: Can’t find file.
LogUObjectGlobals: Warning: Failed to find object ‘Class /Game/BSEditor/Blueprints/GameMode/BP_BSEditorGameMode.BP_BSEditorGameMode_C’

my question is :

  1. we’d like to set the default gamemode_B for A_level, and how?
  2. we’d like to load some uassets in B during hotload A_Level.pak, it seems the original game path is invalid, how to resolve this problem?

many thanks.
