I’m a beginner of Unreal Engine and I’m Japanese. I’m sorry, I’m not good at English.
My character does not move when I move from the title level to the game level.
It moves when I play on the game level.
Character movement is written in blueprints on the player controller.
The title map and game map have different player controllers and game modes.
I don’t know what to do.
I look forward to working with you.
