How can I add a texture or effect to a weapon?

[KommissarReb]

For context, I'm trying to make a plasma gun where a portion of it will have Mace Windu's purple lightsaber where I want the effect to be.

Code Select Expand

Texture = "violetlightsaber"
AddonAttachJoint       = "hp_fire_lightsabre"

I put the above text at a null called "hp_fire_lightsabre" which btw isn't the hp_fire because the hp_fire is in a different spot. I've seen BF2 maps where Kylo Ren's lightsaber has it's side blades, which makes me think I can do this somehow.

Is what I'm trying to achieve possible? And if I can't use the lightsaber texture as a glow effect, what would I type in for some other kind of special effect?
