[Uh-Nu-Buh]

If you are too lazy to make your new evil demonic SantaKnight have a two image sword movement, then here are some easy ways to get the two primary benefits of a second sprite: aesthetic, and to see which unit is doing what on the battlefield.

1. Open your first sprite in The Gimp (SantaKnight1.tga in this example).
2. Script-Fu-->Alpha to Logo-->Alien Glow accept the defaults. Now SantaKnight is a Green Glowing Action Enigma, easily discernible from the non-active units, and startlingly aesthetic. Beautiful even. Good for SantaKnight, because he is a demon from the Green Dimension, but only reveals himself in the depths of combat.
3. File-->Save As-->santaknight2.tga

2a. Alternative. Script-Fu-->Alpha To Logo-->Frosty, good for jotuns, or nords, or van, or any really cool race.
2b. Glowing Hot--good for hot races, radiating races, abyssian types.
2c. Neon is pretty snarky.
2d. Particle Trace is cool for mage types who might be casting spells.
2e. For Warriors, try this: Filters-->Blur-->Motion Blur. You cannot beat Motion Blur for lazy but effective #spr2 images for warriors.
