Changing the unit shadow dynamically?

Hello
I was wondering, how do I change unit's shadow when in game?
I saw it somewhere, I just dont know how they did it :S
Thanks

where?

To See or not To See, that is the question...

Don't give it a shadow in the object editor, then create dummy units with shadows and move them to the position of the unit. Could also do it by playing with images; Deaod discovered that a few days ago.

Basically, I'm doing some kind of particle system. What I wanted to do is: the higher the particle is, the smaller the shadow.
I can't remember D:
It has been done just the way I described before, I only remember myself wondering about how was it done.
It has been a few years back though

Maybe it is related to PandaMine's AMHS? It has a Shadow Engine, but I don't know what it does
