lighting/glowing help

i am making a futureistic gernade type thing and tying to make it glow inside and not have any other lights interfear with the green glowing light any suggestions? heres the picture

You can paint the inside with vertexcolors, and in the material buttons, press “Vcol Light”.

Use halos, make an object like a UV sphere with many faces and click the halo button.

I think that would work better. Ditch my idea about vertex paint.

You mean, uh, something like this?

yeah like that! cool thats what im looking for

You could probably do something similar to what was said in here:

I made that a month ago when someone was talking about making Pumpkin Bombs. I used halo on a UV sphere to get the glow.
