In this tutorial, I answer some of the questions I got on the Displacement Map effect and how to use it. With the displacement map, you can create many different effects such as heat waves for a desert or flame.

If you want to create distortion for your laser from the Dubstep Guns tutorial, precompose your final laser and make sure fill it with red so you can use it for a distortion map. Then apply the Displacement Map effect to a Adjustment Layer and set the Displacement Map Layer to your laser layer filled with red. You now have distortion following your lasers.
