How can I create shadows to hide in, like in Madd Dogg's Rhymes?

If you remember correctly, in this mission you could use shadows to enter stealth mode, I would like to know how exactly these shadows are generated so I could duplicate that process and use it in other parts of the map. Thank you.

I think that's vertex colour

The color must be by vertex color, but if you paint a whole model black with vertex color it will not result in a stealth zone, how do I create a stealth zone then?
