[Particle Trail] Trail not rendering when very close to an actor

[Background] Hello, I have set up a particle trail to use on an enemy - intended to appear on the arms when it plays an attack animation.

[Details] The trail works as desired except when the player (or player camera, this is a first person game) is very close to the enemy as the animation occurs.
This distance is < 2m.
The material is ultra-basic, a full white square sprite, two-sided, no other effects.

[Problem] The issue is the player should ideally be close to the enemy when the animation and trails are visible.

Is this just a limitation with the trails or is there something I am doing incorrectly?

Thanks for any input!
