Place two lights in the exact same location. One will have the normal intensity that You want to illuminate Your scene & cast shadows. The 2nd light is less intense and doesn't cast shadows.
	Create a ring of about 10 lights each at 10 percent intensity in a ring. These will create soft shadows as if from 1 to 100% intensity light source. It does slow down rendering a little to have that many more light sources to have to calculate.
	Simulate soft shadows by using a bunch of lights closely placed on a plane (not a plane object, just a mathmatical plane) perpendicular to the stuff You want rendered. You may get some banding doing this, but with enough tweeking, the results are pretty good. Note: The total amount of light coming out of this light-pack should add up to no more than 255 in any one color if You're using non-diminishing light sources. For example, if You are using 10 light sources and you want a white light, set all the color params to 25.5. It's easiest to build all the lights by using axes in the detail editor and them group them (don't forget to make them all shadow casting).
