I read that it is possible to create cheap (performance) effects by using animated vertex colors . . . But how can i animate and export them for a gameengine?? I'm working with Softimage XSI and 3dsmax . . . every tip will be appreciated! thx

Well, as a guess (Because I've never done anything remotely similar to this), I'd say to do it in the game engine's code/script or whatever. If you can use MaxScript in your game engine (Again, not sure if this even works), then you might be able to do that...

I'm so confused.
