Hello, I am new to unreal engine and I recently created a third person template game and I merged stuff from a different project folder into the third person template game. I see the new content that I added but I can’t drag the vehicle blueprint class onto the map it has a red circle that is crossed out saying I can’t do the action. My ideal game I’m trying to create is a game where you can walk outside of your vehicle and also enter into it and drive around. I’m attempting to re create a game that I used to play back in the old days but only new feature its going to have is the ability to walk outside of your vehicle and quite possibly have actions outside of the vehicle that the player can activate.
Hi @Tactical_Force ,
Welcome to the Unreal community!
What’s happening is that, if you open it, you’ll see a message saying the Blueprint lost its parent class, which means it has no logic and can’t be placed in the world
To fix this and use the Vehicle Template, you need to enable the Chaos plugins:
-
Go to Edit - Plugins.
-
Search for Vehicles and enable:
- Chaos Vehicles Plugin
This is the core of the Chaos vehicle system.
It gives you the main classes (WheeledVehiclePawn, ChaosWheeledVehicleMovementComponent, etc.).
You absolutely need this to place a vehicle in the world and make it move with physics.
Without it, your vehicle Blueprints end up “orphaned” (as you saw). - Chaos Modular Vehicle
This is a more advanced, modular vehicle system.
Instead of a single movement component, you get separate configurable modules: engine, transmission, suspension, wheels, brakes—all editable individually.
Only worth using if you need fine-tuned adjustments or more realistic simulations. - Chaos Modular Vehicle Examples
This is just an example content pack.
It includes pre-made Blueprints, car meshes, wheel setups, movement configs, and test maps.
Useful as a base or reference for building your own vehicles.
- Once you enable them, the editor will ask you to restart.
- In the bottom-right, you’ll see an option to Import the vehicle content, “select import”
- After importing, if you reopen your BP_Vehicle, you’ll notice it now has logic and the Pawn icon. At that point, you should be able to place it in the level without issues.
I’ll also leave you with:
- A video tutorial on how to Enter and Exit a Vehicle.
- Setting up the Chaos Vehicles Plugin
- The official Chaos Vehicles documentation in Unreal, which is a great complete guide.
Hope this helps! And if you get stuck, don’t hesitate to ask in the Unreal forums. Good luck with your project!
