Not to change the subject from volumetric lighting...

I have been playing around with point style lights in Superfly, and I think the results are pretty good. There are three of these lights in this scene. 2 squares, and a ball.

This is how you do it.

Apply this shader to a prop, and use it as a light. You could think of this as an area light, but it has some major differences.

Value 2 in the Cycles Math node is the cutoff distance of the light. I have no clue what the settings are (metric, imperial, etc) And it does not seem to match any of the default Poser UI settings.

Blackbody is the lights temperature, based on one of Planks Law's. You can substitute a color for this as well. IE: for a specific color light you want that blackbody can not produce.

The transparency node is technically not needed and is more of a place holder if you decide to stack multiple emitters onto the same prop. Still experimenting with that, with questionable results....  Not having the transparency node will still default to zero, which is basically the same thing. It just makes more sense to have the transparency node there.

The lightfalloff node is what controls the distance curve of the emissions, brightness, and smoothness. It doesn't work the way you would first think it does either. Experiment and see for yourself.

Strength is not in watts, lumens or any setting you are used to, it is just a strength output that does not calculate anything based on other settings, sizes, etc... A small emitter may need to be set in the 1000's. A large one may never be set much past 1. Smaller emitters will take far longer to clean up as well. (Still missing light portals to deal with that)...

You can change what type of light falloff you want simply by plugging it into the Emissions Strength. And again, your not going to get what you first might assume.

Smoothness is a double edged sword, and takes some experimenting. Small emitters that use smooth may take far longer to clean up, so leave that at 0 for small ones. On larger emitter lights, smooth will crush the lighting and dull blowout if it is a bright light. It works a bit differently in Cycles, and on a different scale. So you may have to play with that versus what you get in Cycles.

Some of this can be applied to actual Poser lights in Superfly, some of it can not and has to be done this way.

And lastly, yes, that is LaFemme again.....
