Thanks for your reply. The inputs to control the vehicle work well. Here’s more details about the project : I created a project based on the third person template. Then, I added in the project the default Unreal vehicle asset. When I choose the gamemode of the vehicle for the level, I start the game with the vehicle and I can control the vehicle with no problem. And then I possess the character and it doesn’t move. And when I switch back with to the vehicle I can control it. And vice versa : when I start the game with the gamemode of the character, I can control it. When I possess the vehicle I can’t move the vehicle. It’s like the gamemode define what pawn I can during all the game, even if I possess another pawn.
