Prewarm Trailrenderer

I’m using a trail renderer for an effect on a projectile. All works great except that the trail renderer doesn’t appear at all until my object has moved a certain distance.

See the image below:

2 is a projectile (off screen) that has travelled away from my weapon, and the trail you see is for that projectile.

1 is a projectile that has just been fired.

The faded end of the trail renderer is where the trail renderer always starts. Is there a way I can make it start at the projectile’s starting position, kind of like a particle system’s pre-warm setting? (i.e. the end of my gun barrel)

Here are the settings on my trail renderer:

You won’t be able to “pre-warm” with that trail rendrer, but pre-warm is an option with this 3rd party trail renderer
