it would be hard to get a good screen shot of it, what it does is it works like the grow modifier in 3ds max causeing a version of the model that is scaled up via moveing each vertex along it's averaged normal, it looks better on some models than others, like the mantacore, I think it looks good, on a herc (1) not very good, I'm thinking the explosion hull effect is going to be the way to go, but before I go into working on it too much more, I'm going to wait for some more feed back, specificly people who know how to make good looking explosions (in 3ds) and what they'd do.
I think I'm going to talk to the art people about this
