The Value_Range parameters in the gradient do exactly the same thing as
the change_range. You must increase the max_value to the maximum
distance you want the gradient to affect the light, in XSI units.

Thanks both of you for the help - however it seems my brain is running
on numb today as I can't get it to work with your exact steps.
I had to mix both 'recipes' to make it behave correctly so I now have:
ScalarState:ChangeRange:MixerGradient:Softlight
Francois, I can't get it to work without the ChangeRange - does that
makes sense?
Graham, the part with layering texture and volume seems really nice,
I'll have to try this out ;-)
Thanks,

set the light up how you want same way as with curves in maya except
with a gradient:

for post lighting u can fake neg by shifting 0 to half way up the
available but depth, then in comp shift it bak. (also this way u can
get 6 lights instead of 3 using standard post light technique.)

In the Render Tree, plug a Scalar_State (ray length) in a
Mixer_Gradient. Then plug the Mixer_Gradient in the light color.
Adjust
the Active Range in the gradient (third tab). You will get a good
control over the way the light lights.
