Oh I'm not ignoring you, it simply didn't work. I thank you for your help though.

Code:

---

  
action icx_terrain
{
	my.material=mtl_terrain_multitex;
	my.polygon=on;
	c_updatehull(my,1);
	my.cast =off;
}

I put two bipeds in and saw the shawdow casting on the other ped, but not on the iceX generated terrain.
