Invis unit question

Hi. Is it possible to make a unit only visiable to one person (even though the person is allied to other people)?

There's no way I can think of, unless you don't actually use alliances, but somehow simulate the other aspects of an alliance using complex and annoying triggers.

I'm quite sure altering a unit's vertex coloring with the use of getlocalplayer doesn't cause a desync, but that would still only make the model invisible to other players, the unit would still have it's shadow and would show on the minimap, unless you would disable those things for that unit-type, but then the player that controlls the unit would have difficulties finding it... and, if the players had shared vision, the allies would still see the unit's line of sight, unless it were completely surrounded by friendly units.

if you disable shared vision, the invisible unit would only show up for his owner.
so simply disable shared vision for all players.
