Hey Yosephu! 👋
The cars come with detachable parts like the doors and bonnet by default, but the engine isn’t set up as a detachable mesh.
That said, it’s pretty easy to separate it yourself in Blender, Maya, or any other 3D software. Most of the car parts are already modeled separately — they’re just merged together in a few places to keep the model clean and game-ready.
So you should have no problem removing the existing engine and replacing it with your own! 👍
