Create a collider ( SplinePathMeshBuilder)

[Jake]

Hm,

I just checked with the MeshBuilder example. I added a MeshCollider to the RoadPath GameObject and additionally this script (MeshColUpdate.cs):

Code:

using UnityEngine;
using System.Collections;

public class MeshColUpdate : MonoBehaviour {
    MeshFilter mFilter;
    MeshCollider mCol;

    // Use this for initialization
    void Start () {
        mFilter = GetComponent<MeshFilter> ();
        mCol = GetComponent<MeshCollider> ();
    }
    
    // Update is called once per frame
    void Update () {
        mCol.sharedMesh = null;
        mCol.sharedMesh = mFilter.mesh;
    }
}

Of course that's horrible slow, but the Collider updates properly when I change Extrusion parameters or modify the underlying spline. Can you test the above script with the example scene, just to be sure this behaves the same on your side?
