Hey,
Search for ‘”muzzle” on the forum search.
When you created a muzzle fire, its pretty simple. Just add it to your to your gun. It only needs 1 or 2 frames of a second. Sins it only needs 1 or 2 frames, you can try to make it in photoshop. Maby add ome light to the actor, see andrew kramer tutorials for that.
