Bone list and Bone Scaling notes.

this has been adapted from the textools reference doc page of the same title, created by sel. this has not been fully updated for dawntrail, and some information IS missing or outdated. I will correct when I can.

As a note. this list is based off the old bone list. Dawntrail completely redid the entire face skeletons, so please use the face bones specific list for all DT updated heads. The First three tables are a list of Vanilla bones. 

Bones with <a-e> are multiple bones in sequence, such as sebo (spine) bones. Bones with <l/r> are left and right bones such as leg bones. bones with <f/b/s> are Front, Back, and Side bones, such as skirts. any bone with _ex in it's name is an Extra bone, and will only exist when the associated skeleton metadata is loaded. This is most commonly seen on hair, but has been used on gear on extremely rare occasions.

Dawntrail Face Bones

As a note, not every bone can be manipulated or scaled outside of gpose, (such as with Customize+ for normal gameplay). furthermore, many of the facial bones are kindedriver or "Helper" bones, and are either not meant to be touched on thier own, or are meant to provide small adjustments after moving the main bone. If you are not posing an old NPC head, you should only use the face bones listed here, and not the ones in the above chart. 

Some bones are labeled GPOSE ONLY bones. These bones will only ever work in gpose and in cutscenes, and trying to alter them in a non-gpose only setting such as customize+ will cause these bones to immediately revert when leaving gpose. Do not use these for scaling outside of screenshots. This is not fixable and is a game limitation. if you want to dialate or contract your pupils for out of gpose, you will need to look into eye mods

Other Vanilla bones

This is a table of other VANILLA (unmodded) bones that didn't neatly fit in any other category. This also includes bones in Anamnesis' bone list that do not appear on DT updated heads, and are assumed to be Pre-DT fave bones. these bones will be marked. 

As a note, there are Many more bones than here, but most of the bones not listed are _ex bones, these are "extra" bones that are not always present. EX bones are generally only seen on hair, but in rare occasions may be present on gear. Gear EX bones will be listed WITH THE EXCEPTION of the longer wedding veil's EX bones because there are TOO MANY. These bones are also only present on the longer version of the wedding veil which is normally only active when inside the sanctum of eternal bonding. 

This chart will not list the sage or reaper scythe bones, as there are multiple sets per weapon type, and it's too much work for me to check all of them manually. Sorry.

The EX section of this chart IS incomplete, and likely always will be. This chart will not include Hair or Weapon EX bones, as there are too many, and they are being added too often.

Modded Bones

This is a list of bones that ARE NOT PRESENT in vanilla skeletons. These bones will ONLY exist if you have the accompanying extra skeleton mod, and have it set up properly AND a mesh rigged to these bones. Most of these bones were created for the purposes of NSFW animations or physics, rather than posing or scaling. That said, with some work, they can be used for those purposes. All IVCS1 bones are included In Other newer body skeletons such as IVCS2, YAS, and Skelomae for the sake of compatability. For other compatability questions between newer skeletons, Please check your preferred skeleton's documentation. 

Because of the nature of modded skeletons, and the fact that these are not only capable of changing at any time; but also can be added to by anyone. This WILL NOT be a complete list. This list will only contain the basic bones used by most body mods. THERE WILL BE BONES AND SKELETON MODS MISSING FROM THIS LIST. THAT IS INEVITABLE. 
This will NOT include any "exotic" bones or modded bones made for one specific gear/face/whatever mod, as it's again, more effort than it's worth for me alone to keep up with.

Bone scaling notes

Many in-game models share the same model, but scale the bones to fit the body shape they want. this is a list of known and confirmed scaling values that match up correctly with the in-game versions.

These are meant to be used with posing tools/plugins, with Customize+, or when testing your models in a modeling software to ensure that things don't clip at larger bust scalings. 

At this time there is only bust scalings, but we will be happy to add other scalings as people find them. Keep in mind that not all gear pieces are weighted equally to the breast bones. Many newer gear pieces are weighted to 50% breast influence instead of 100%. For these you may need to go up another percentage category to have the same effect as your racial starter gear or nude.

As a note, these same values will work in a 3d modeling software like blender or 3ds max. for 3ds max, move the decimal point back 2 spaces.

All races have racial scaling applied to them, these values are accurate for Middie F, but some races such as viera/roe and Au Ra may have slightly different values due to thier racial scaling. This chart is meant as a rough guide.
