You cannot set network ownership on anchored parts. Ensure the PrimaryPart of your vehicle has no active welds to anchored scene objects. If you want to build on top of this system, let me know:
To create structural barriers that explode beautifully when struck by a high-speed vehicle:
: Not enough downward force or suspension too stiff. Fix : Add a downward raycast that applies a small force toward the ground, or adjust spring/damper settings.
So you want to make a car zoom down a steep incline in your game? Whether it’s a racing level, a stunt map, or a physics puzzle, getting a car to drive down a hill smoothly requires a mix of gravity, ground detection, and a little bit of traction control. In this post, I’ll walk through a simple but effective script (using Unity-like C# as an example, but the logic applies to Godot, Roblox Lua, or Unreal Blueprints). drive cars down a hill script
Driving down a hill feels great when the car maintains contact with the ground and picks up speed naturally. Start with the basic script, then tweak the gravityScale and motor force until it feels like a real downhill rush.
rb = GetComponent<Rigidbody>(); // Increase gravity effect for downhill realism rb.useGravity = true;
public float motorForce = 1500f; public float brakeForce = 3000f; public float gravityScale = 2f; // Extra pull downhill public LayerMask groundLayer; You cannot set network ownership on anchored parts
Once the basic downhill driving works, level up your script with these extras.

Use AlignedPosition constraints instead of BodyVelocity for realistic suspension compression on hills.
Now go ahead – copy the code, build your hill, and let those cars roll!
