Need help creating clouds

I have no idea how to go about creating my cloud system, I need help. I DO NOT WANT A SKYBOX!, I cant stand those, I want some sort of mix between realistic and cartoonish and I need them to be able to be changed easily for weather effects and such. I have absolutely no idea how to go about this, I am currently using particle systems but I am afraid that will not run well on lower end computers

This sounds like more of a design question than a scripting question. The basic “make clouds drifting overhead” script is going to involve something ilke this:

  • make a cloud prefab (or many of them)
  • make a script to spawn them overhead
  • for weather changes, swap them out with different-looking clouds
  • for extra credit make them move along with the breeze

Don’t worry about performance until you determine a problem, otherwise you’re wasting time on fantasy bugs.
