When building dark colors, especially black, blend in with the background of space. This texture pack is designed to make it easy to see what you are building without the background looking ugly as sin or conflicting with other colors. To make it work you need to unzip the contents to your "StarMade\data\sky" folder and disable procedural background.
DO NOT USE THIS FOR PVP!!! I will not be responsible if you use this to cheat and are caught.
