Describe the bug
GunTrails can only be seen from an angle, which means that if an player shoots a gun, he cant see the trail. However if the player moves fast enough away from the origin of the shoot, the player may be able to see the trail

To Reproduce
Steps to reproduce the behaviour:

1. Take any gun (e.g. Barrett .50 Cal)
2. Dont move and shoot the gun
   Now you are observing that you cant see a trail

To get a glance at your trail

1. Take any gun (e.g. Barrett .50 Cal)
2. Move sideways (e.g. to the left)
3. Shoot
4. After roughly half to one second (depending on the movement speed) the trail appears at the side your not moving to (in this example on the right).

Expected behaviour
A clear an visible trail is always visible

Screenshots

In this picture i was moving to the right. The gun Trail is barely visible at the left (Surrounded with a red box)

Additional context
As far as i am concerned, this is a problem of the way guntrails work. They are a 2D object, with width and length but no height. This means that observing the trail at its origin, because of the missing height, nothing is visible
