yesterday I asked chatgpt about car not moving at all even front wheel not turn he told me about pivot point where to fix it
To check that the pivot point for a mesh is set to the center of mass in Unreal Engine, follow these steps:
Open the mesh in the Static Mesh Editor.
Click on the “Details” panel on the right side of the editor.
Scroll down to the “Static Mesh Settings” section.
Expand the “Body Setup” dropdown menu.
Click on the “Mass Properties” dropdown menu.
In the “Mass Properties” section, you will see the “Center of Mass” field.
Click the “Recenter” button to reset the center of mass to the default value, which is the geometric center of the mesh.
If necessary, adjust the center of mass to a different location by using the “Location” fields.
It is important to have the pivot point for the mesh set to the center of mass so that the physics simulation can properly calculate the movement and rotation of the object. If the pivot point is not set to the center of mass, the object may behave unexpectedly in the physics simulation.
The center of mass of a vehicle can vary depending on the shape and weight distribution of the vehicle. However, in general, the center of mass of a vehicle will be close to the center of the vehicle, and usually slightly towards the front due to the weight of the engine and other components.
