How to use the Template texture
Take a picture of Luigi (Or Mario since it's the color code that
matters) using whatever color code you want (or use random colors),
then use the darkest part of the color in the dark green section,
and the lightest part in the green section. Next blur the image, best
if using Gimp's Blur tool and is set up to the biggest size and then
move the mouse around to blur the image. You should get a similar
texture to the others. The beauty of this is that you can have a
solid color or an inverted one, and Mario will have no shading/backwards
shading ingame because the model actually has no shading in game and
the texture is just normalized so it rotates with the camera to make
his "shading," almost exactly like how Mario's shading worked in the
actual game, just in that game it was polygon coloring, which we can
actually change the color, but it's easier, and more
effective/n00b-friendly to just use a texture.
