As noted, I'm using Blender Render for this little experiment.
What I've been trying to find is how to get a straight glow on an object. Volume materials seems closest to what I've been able to replicate but unfortunately, emission light does not work inside volume materials.
If there is a better way to do it in Blneder Render, how can I make it glow more appropriately along the area surrounding it? And how can I make it so the edges serve as an actual light without resorting to using many smaller lights?
Another good example is like this alien blaster, the light surrounding the blue. https://www.youtube.com/watch?v=EAhRiv-FKbI
