I have been working on a pack of various particle systems that I plan on releasing if I can finish it, which I should be able to. Anyway, it is split up into 8 categories. Fire, explosions, beams, smoke, sparks, impacts, magic, and muzzles. My goal is to have at least 15 particle systems in each category, and if all goes well, even more. It will also include the vector fields that I created. The assets are very well organized and named, all emitters are named, and all categories have their own materials folder for category-specific effects and materials. Here is a video I posted to youtube showing what I have so far!

Let me know if there is something specific you would like to see, and I will see what I can do! Also let me know of any improvements or suggestions you have. I am not extremely advanced when it comes to creating materials, but I am learning. I am having a lot of fun making these, so I hope you like them.
-Update-
Here is an update video showing the newer effects and changes!
