Today, I’ve learned that I am absolutely TERRIBLY when it comes to particle systems. I’ve got a couple of materials set up - I started off following this guide: > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — ue4community.wiki! You will be able to find content from the official... I’ve made my own modifications to keep it straight and a single beam (not doing the weird things like the 3 beams were doing), but I’m not entirely happy with the result - the beam is too wide, and I’m not sure how to control the regularity of the pulses on it. My goals: 1. Have a little “ball of light” at the end of the beam - I have a a texture that’s just a white radial gradient on a black background, but I’m not sure how to use it. 2. (Perhaps) Animate the pulses so they move from source to target along the beam at a defined speed. Whether or not I do this is still in question - I’m aiming for a mobile platform, and I’m not sure how taxing this would be. I’m also not sure how difficult it would be. If anybody could help me achieve these goals, it would be greatly appreciated. Thank you!
