Particle System - Explosion, Smoke, Dust...


I’m new to the Particle System so i don’t know much. Its it possible that someone could pass me a simple Explosion asset or explain a way to make a simple explosion in the particle system? Some smoke to follow that would be nice, but its not to much needed.

I would also like an asset or a simple way to make footsteps dust when you walk around.

If someone could pass me a site with the most simple assets possible to get theses features, and also lasers, weather and etc would be great.

Thanks for the attention.
