If you're referring to the Unity Trail Renderer then yes, you can. The Deathmatch AI Kit does this and you can do this by adding the Trail Effect module to the Extra Module Group.
Thank for the response. I don't see trail effect as an option on the Extra Module Group. I only see Scope, Dry Fire Substate, Look Sensitivity, Slot Item Monitor, and Prevent Dry. Is that an add on?
Oops, you're right. We don't have a module for a trail with the shootable action. There is a tracer under the HitscanShooter module which is what the Deathmatch AI Kit uses. For the Trail Renderer you will need to create a new module similar to the melee one.
