Creating visual effects using procedural textures/modeling

Question

i'm a beginner in Unity, i've learned in Graphics course about algorithms of procedural textures/modeling. I would like to use these algorithms to create visual effects - fire, smoke, lighting, snow, etc.. Does someone knwo how to create those effects using Perlin Noise, L-System, Voronoi or any other procedural algorithm in Unity? Better without using prepared prefabs or Particles System.

Thanks!

On a side note however, using premade effects from the assetstore etc is not a crime. In the industry it is normal that you dont create every asset or piece of code yourself.
