And if the palette goes beyond the EA colors and/or more swatches and/or sort differently by cc eyes creators, it will be like picture above.
So originally, most nondefault eyes are made with the sorting order from 0 to 100+, which gonna make 10 different styles of green eyes in around same spot of EA green eyes, for so they mostly sort by colors. I really apologize for my lack of knowledge when writing this tutorial.
EDIT: Sorry to any people follow this tutorial before I edit this, you should follow this tutorial instead for faster method, both works fine but the other tutorial is much faster and easier. If you are using 2+ non default eyes like me and you are borthered by the swatches are mixing up or hard to find the eyes you want without having a headache.
