Hi,

I'm trying to make a glowing ball of light such as a car headlight or glowing sun.  However I can't seem to make the edges fade off of my globes.  They look like light bulbs (hard glass edge) not the diffuse fading out effect of a sun or headlight at night. I have tried using semi-trasperent png but doesn't work
Can someone pls help! This seems like it should be a basic thing but I can't find a tutorial or anything to help

I've made a primitive of a globe.  Now how do I make it bright in the center and fade off into transparency from the outer edge?

 
Like this.... (actual picture of headlights)

Most of what I have seen along this has been postwork (seen a couple tutorials). I know there are a couple products that have a prop that is used to mimic volumetric lighting. That I know of there is not an easy way to do this in D/S. I believe its AurthorPendragon over at DAZ that has a product that lets you get to the options to adjust the falloffs of the lights in D/S but I have not played enough with them to say if they will do what you want.
G'luck

This may be a bit late, but if you want the effect to be applied to the globe itself you could try JLG's free shaders . There are a couple of "Glow" ones that might work. I used one of 'em for a pic in my gallery ("Abracadabra").
