This particle is the result of the "Learning Niagara Particle" tutorial series which can be found on my YouTube here:

I made this particle set in order to have my own custom bullet assets that I could use as a base to create other projectile related effects in the future. I tried to think about what the absolute minimum amount of particles would be required for me to make a convincing looking semi-photorealistic muzzle flash and hit effect, and I ended up with 4 main components. Sparks, Muzzle Flare, Explosion, and smoke. Those 4 things essentially get me 80% of the way. Most of the heavy lifting is done with some simple moving material tricks, but overall I've been fairly happy with how it turned out - It was a fantastic learning experience, and I can't wait to learn more and improve it as I pick up new skills and tricks :)
