I watched tutorials on how to create fog within bounding boxes, but the fog is static. I'm trying to create a scene of an airplane where the camera is looking down on the clouds, and the clouds should be moving. I was going to try and make the clouds in a similar way as I made the fog (with bounding boxes) but is there a way to make the clouds move? The airplane is going to fly through the clouds so it's important that they are 3d and not just a plane. Is there a better way than using bounding boxes?

    $\begingroup$ You could try noise and density with a principled volume, while changing the vector $\endgroup$

As Yohello says you could use the Principled Volume and plug it into the Volume socket of the Material Output. Here is a basic way to do it (perhaps not the most realistic solution though, but you'll find other ones on youtube or maybe someone will propose here?):

  • Create a basic elongated shape, subdivide it a bit, give it a Subdivision Surface modifier.

  • Create this node chain: Texture Coordinate > Mapping > Noise Texture > ColorRamp.

  • Plug the Noise Texture into a Vector > Displacement node to give it a bit of 3D relief (don't forget to enable the Displacement > Displacement Only option in the Properties panel > Material > Settings > Surface).

  • Plug the Noise into the Density socket of the Principled Volume.

  • Now play with the Location values of the Mapping node in order to make the cloud shape evolve through time.
