Has anyone ever painted star wars lightsaber minis and could tell me how to do that "electrical" light sword type glow effect with paint?! or is it just impossible?!
I don't know about creating the lightning effect in paint; I think expert painters might be able to create a passable effect, but not me.
Here's an idea, which would also require expert skills, but more in the modeling side of things:
-make a mold of the lightning claw marine's hands.
-cast the hands in a transparent material, like two-part resin.
-drill a hole and insert LED lights (perhaps wired to a small battery in the base?) into the hands, replace plastic hands with these.
-then paint back over the rest of the hands. This would leave some lightsaber-y claws protruding. Maybe mix some blue food dye in the resin.
-For the really advanced, paint metal back over the claws, leaving 'lightning arcs' shining through.
I bet there are people who are into Space Hulk enough to do this, and have the skill and patience for it. Maybe it's already been done.
