Hey Adam, we are looking at a baked RayFire (http://www.mirvadim.com) animation working inside the Unreal Engine. Almost worthless for gameplay but awesome for cinematics.
Well it sort of took forever to get it working but its working. Thanks to Gizmosan for the explosion FX. Going to be doing alot of this for our lil project. Cheers! [ame] http://www.youtube.com/watch?v=jMNEEfyIIJg[/ame]
