Volumetrics (Fog, Clouds, etc.)

Hello!

I’m currently making a basic flying game and I want to have clouds in it.
How should I approach this? Is it even possible to have it run at a reasonable framerate?
I’m currently thinking of having a number of semitransparent pictures placing them on cubes and filling up an area of a cloud.

Thanks in advance!

There are tons of ways to have clouds in a game, from simple 2D billboards to volumetrics computed using raymarching in shaders. The right answer depends on the fidelity you need, your target platform, etc. There are already a lot of topics on this, just google for unity clouds. If you want a bigger set of things to read up on, search for “realtime clouds”.
