Anyone know any good techniques to make a wall of dark clouds?
Sky sphere solutions won't work because I need an abrupt change from
clear sky to dark, stormy clouds right in the middle of the scene.  The
only example I can think of is an obscure TV movie called White Dwarf in
which there were two lands seperated by a monsterous wall.  There was
a scene where they were looking at the wall from the 'lighter' side which
had clear weather and above the wall on the 'dark' side were the ever
present clouds.  Basically just a very abrupt change.  I need to be
able to control transparency because I want to use a lightning halo I
made with it.  TIA

You could try a cloud height field... I think there was a post using
that technique (and asking about fog), but I don't remenber exactly.

Well, a sky_sphere might work if could use a gradient texture blend (abrupt
in the middle) in the direction your camera is looking.
