The NormalToLocal method of the Transform struct is used to convert a normal vector from world space to local space. This is particularly useful when you need to transform normals for lighting calculations or when working with objects that have been transformed in the world.
To use the NormalToLocal method, you need to have a Transform instance. Call the method with a Vector3 representing the normal in world space. The method will return a Vector3 that represents the normal in the local space of the transform.
// Assume 'transform' is an instance of Transform Vector3 worldNormal = new Vector3(0, 1, 0); // Example world normal Vector3 localNormal = transform.NormalToLocal(worldNormal); // localNormal now contains the normal vector in the local space of the transform
