Align normals of an object to a single point

Hi there,

I am doing a lot of work with Element 3d and crowds at the moment. The direction of each particle is set by the normal of the vertex. One vertex = one particle.

I need a script that will modify the normals of one object so that they all point to a single point, this could be a null or helper somewhere else in the scene.

I can do some scripting in other languages but I'm no good at maxscript.

Can anyone help with this??

Thanks

Will
