No information about assetbundles?

I looked this stuff up before asking it here and simply couldn’t find an answer… The problem is that when I download an assetbundle from the internet, the mesh collider doesn’t work. I literally need mesh colliders for this project and my character keeps falling through the ground :frowning:

bruh i fixed it :confused:

public class AssignMeshCollider : MonoBehaviour
{
    void Start()
    {
        GetComponent<MeshCollider>().sharedMesh = GetComponent<MeshFilter>().mesh;
    }
}
