The blaster is works with drivers and a deformed mesh with flash material on it. When you want to see some gunfire you have to turn the Flash Collection on and press play. The way I do it is render up until you want to start firing, then take that frame number and make that your new start frame. Next activate the Flash collection and render then next amount of frames. When you reach the frame you want to stop firing, turn off the flash collection. It's pretty easy once you get the hang of it. I made this because I like animating movies and blasting stuff but don't like dealing with complicated flash animations.
