[Sammy-ROCK!]

I can only change the entire model color.
SubZero I call him "The Incredible Zombie" xP
Also Samurai if I use KeyValue using "0 255 0 128" like you said alpha gets no effect.
Tried: DispatchKeyValue(Tank, "rendercolor", "0 255 0 128");
The alpha value simply does nothing like that. If it worked Tank would be half transparent.
