I've made a set of custom melee weapons (staff-like in nature) in blender and they've been successfully added to the game.

However, I think they're lacking a certain "pizazz", I'd really like to add an effect to them (like lightning or flame or any others you can suggest).

Can anyone tell me how this could be accomplished? Or even a point towards a tutorial would be helpful.

Thanks in advance for any help =D
