Terrain Material for 'footsteps'

[Flexman]

I wonder if anyone had any ideas on how to tell what terrain texture you might be walking on for doing the classic "footstep" audio effects?

 

A function like int GetTerrainMaterialXY(x,y); ???

Well i can get the textures on the terrain but I cannot figure out yet how to determine which one is "on top". All the textures appear to be assigned to one material in the texture slots 0 thru 9 (assuming you are using all 5 diffuse textures and their normalmaps). I assume you would have to do something with the alpha layering or maybe the "colormap" that is created.
