generating clouds

does anyone know a simple way to make moving cloud textures? I have tried jit.qt.effect’s cloud but I want to make something more like the photoshop cloud effect (to cover a whole matrix). I’m sure it must be simple, but i can’t work it out.

thanks,

oli

combination of few jit.bfg objects is super for that!

an example, quite slow at initialisation but after that it should run
smoothly:
