Hi Ellix, Welcome to the Forums,
You might need to enable the ‘Chaos Vehicles’ plugin in your 3rd person project.
There’s a new input mapping system in UE5 called ‘Enhanced Input’. Here’s a basic way to switch input contexts.
Lyra is a completely different beast than the 3rd person template, but reading this tutorial might give you some more ideas.
Let me know if you are still having trouble with this!
