This is a vanilla texture edit to make shack floors appear less repetitive. Foundations, stairs, and some walls share this texture, so they will be replaced as well. I used ShackWoodTile02 as a base, and adjusted the saturation and light values of each board. It's not perfect, but I thought it was a nice improvement.
1.0b: Uploaded compressed version (thanks Mr. Dave) 1.0c: Tweaked the color values of the bottom left corner.
