I have to make something similar to blinker.
I did simple example model:
"Bulb" has material - White LED.
But as You see - is not natural, light is sharp. How to simulate dispersed light?
I have to do this by using matierial, not lights.
Dispersed as in light fog with local fall off? I don't think you can as such but you can trun on bloom in the render options for the final render and that sort of fakes what you are after. A point light would do it but that's not a matirial option. There is a very nasty hack using multiple nested bulbs in decreasing sizes, with transparancy but the render time is hidious.
Use a point light where the bulb is. Then turn on the fog option and adjust as required.
That would be the ideal way to do it but he says that he needs to do it with a matirial, presumably because of the limited number of "real" lights the PV engine supports.
Ah, sorry. Didn't pick up on that. Timothy is correct. Bloom is about your only option.
You could try using a decal on the bulb. With the decal you could use a gradient mask which would allow you to fade the light but on the bulb only. Then maybe add some bloom which would help enhance the light scatter effect.
Not sure it will do what you want but it wouln't take long to try it.
