I made a small Unreal Engine plugin for bullet tracers and wanted to see how far I could push it.

The video shows a stress test with a lot of tracers on screen at once.
Goal was to keep it very lightweight and mobile-friendly while still looking good.

You can customize:

color

intensity

tracer scale

speed

Runs well on mobile, PC, and VR.

You can find more info and the plugin itself here (CLICK ME!)
