Hi I'm trying to create 3D clouds in Blender to be used in Unity. Imagine the bubbly-like fx of the flying nimbus in Dragon Ball. Not really sure what the best approach is. I've tried using displacement modifiers and get decent results in Blender. But exporting to Unity is a no go. Are shape keys my only option? If so, what's a good way to achieve what I'm after using shape keys?

You could create a cube, subdivide and smooth it:

Give it several shapekeys:

In Object mode, select a shapekey, push its Value up to 1 and sculpt:

Sculpt the other shapekeys, animate them:

Or you could create your mesh with metaballs that you convert to mesh:

enter image description here

Then give it a Displace modifier with a Cloud texture and an empty as Object:

enter image description here

In the Displace modifier, save several versions As Shapekeys:

enter image description here

Now you can animate the shapekeys, also sometimes do some Shrink/Fatten to inflate the cloud a bit:
