A simple flame prop, to use for flaming swords. Parent the prop to the sword and make it 0.1% scale. When you want the sword to ignite, increase the scale of the flame over a couple of frames. While it is flaming, rotate it by 180 degrees each frame to make it seem like it's flickering. Make sure the flame and the sword don't cast shadows, and parent an orange light to the flame to illuminate the rest of the unit; alter the intensity of this from frame to frame to create a flickering effect. But be careful not to cast coloured shadows onto the ground, as this will screw up the appearance of the unit in-game.
