OnPostprocessGameObjectWithUserProperties no children exist

Hey Everyone,

I have a slight problem. I create a collision class. I'm using this script which should work, and seems to when I put it in the start() method

Code (csharp):

1.  
2. foreach (Transform child in transform)
3. {
4. Debug.Log("Assigning mesh collider");
5. }
6.  

But what I'm doing is to execute this method before the start of the game. on setup, so I created a separate class in the Editor folder called Autorun, which runs as soon as my model is imported. I have one custom property in the model that's used as a string.

Code (csharp):

1.  
2. public void OnPostprocessGameObjectWithUserProperties (GameObject g, string[] propNames, System.Object[] values)
3. {
4. Debug.Log(g.transform.childCount);
5. }
6.  

This seems to return 0 children.
But when I put it in the start() method of the collision class, it returns 1 child.

Is this something to do with the children not being initialized before the game starts? How do I overcome this?

Much obliged
