Chapter 123All you need to do is copy and paste the names of various weapon related properties, such
as mesh, muzzle flash, and pick up sound from the UDK Content Browser to the appropriate
fields in the wizard and click on Next.
This is a great way to get started with learning how weapons work and are
constructed in UDK. Compare and contrast your new weapon with some of
those which come packaged with UDK to really get a feel of how to develop
some weapons of your own without the wizard.
