I am wondering if it is important to follow the alignment points as shown in the extraction guide exactly? For example,

the left eye brow line starts far left at 17, arches to the right, and ends at 21. If that line was reversed, starting far left at 21, ending right at 17, would that have an adverse effect?

Thank you!

Yes. it would impact alignment. To what amount, I could not say.

Interesting. I assume that would apply to something like if the points on the eye were upside down? Left eye with 37 &38 on top and 41 & 40 on bottom in the reference picture. If I were to reverse those, that would have an adverse effect, yes?

Reason I am asking is I am fixing my alignments and sometimes they get all bunched up. As I started stretching them out, I started thinking about the numbers and how vital the placement might be.

Okay, another question. The inner mouth points, 61-65, should they line the inside of the lips or teeth? Also for eyes, just the white part of the eyes, or do I include eye lids too?

I thank you taking the time to answer questions, and very much appreciate all the work you do.

You don't need to overthink/overdo it. If the extracted face looks aligned, call it correct and move on. The model has a certain amount of augmentation built in to deal with minor misaligns.

For training sets I just delete any misaligned faces. For convert, I will fix obvious misaligns, and then run a convert. If there are issues in convert, then I will go back and fix those faces that are causing issues.

Landmarks don't need to be exact. They just need to be 'good enough' to produce a correctly aligned face.

Haha. Yes, I am overthinking it. I will heed your advice. Thanks again!
