WorldViz User Forum - Fog on the horizon

I'm trying to make the horizon foggy so that it doesn't look like
a sharp line between ground and sky. The problem is that the
fog works on the ground but not on the sky. Here is my code:

Code:

from viz import *



go()



env = viz.add(viz.ENVIRONMENT_MAP,'sky.jpg') 

sky = viz.add('skydome.dlc') 

sky.texture(env) 



terrain = viz.add('InfiniteTerrain.dlc',1,'456',0,700,15000,0.005)



grass = viz.add('gb_noise.jpg')

grass.wrap(viz.WRAP_S,viz.REPEAT)

grass.wrap(viz.WRAP_T,viz.REPEAT)

terrain.texture(grass)

terrain.emissive(1,1,1)

terrain.command(1,'',0,0)   

clip(0.5, 100)



fog(2,20)

fogcolor(WHITE)

Is there a way to make the sky foggy as well as the ground?
