【Black Myth: Wukong】Need help for Modding

[ramroyal]

I am a beginner in game modding.
I want to mod Wukong's armor.
I have extracted the model for editing by FModel and imported it into UE5.0.3 because I can't install UE5.0.0 and naming the project "b1" and creating files according to the original path.
After that,I setting check Pak file, Generate Chuncks, allow ChunkID Assignment and uncheck Io Store and Assign Chunk to 1000.
And then I packaged the project (win) in shipping mode.
However, when I put the .pak file into ~mods and tried to view it using FModel, it didn't show up and I test in game it not effect
I would like to know if I made any mistakes in the process. Thank you in advance.
