This mod is a ressource for modders, and I hope it will help people to get into 3d modeling. 
I need your feedback so we might adjust the used zones.

So, what is a part map ?
In FCS, when you create an armor, you can set part map zones.
9 colors are available, 3 are used by default.

So what does this mod do ? 
Vanilla part maps only hide armpits, torso and belly for humans. Hivers actually haven't theirs, and skeleton only have one colour used (only for some parts of the torso. )
The mod makes use of the 6 remaining colors, so you can actually hide the whole body ! If devs add more colours, I'll separate some zones. For example pelvis and legs, or legs in 2 parts (which would help for vanilla pants that clip). 
It also adds hivers (queen excepted) a real part map for them, as they used human's while having absolutely not the same texture pattern.
That means that all hiver races but queen have a new path (so beware for compatibility issues, even if kenshi is well made for handling it). 

Why ? 
Because it extends modding possibility. Want to make a helmet that replaces the body with another one? You can.
Wanna make high heels for the waifu ? You can.
Wanna make very close to body armors without worrying too much with clipping ? You can.

How can i use it for my mod ?
Just check at the pictures to get an idea of which zones are covered by which color. In FCS you'll have to check these colors is you need to hide a part.
For example, orange will hide hands ! 

Complete zones list:

New zones (could change, because i'd like it to be a community thing, for modder convenience without altering vanilla ones). 
Blue : rest of the torso and back, that are not covered by vanilla

Magenta : Arms without hands : https://steamcommunity.com/sharedfiles/filedetails/?id=1670239337
Cyan: feet, at the moment stops at ankle, could cover vanilla boot zones 
https://steamcommunity.com/sharedfiles/filedetails/?id=1670239811
yellow : neck (might add any zone barely used, as the zones should mask everything)
https://steamcommunity.com/sharedfiles/filedetails/?id=1670238084
orange : hands : https://steamcommunity.com/sharedfiles/filedetails/?id=1670239131
purple : legs + pelvis https://steamcommunity.com/sharedfiles/filedetails/?id=1670238954

Unfortunately, head cannot be hidden, that would be even more fabulous for modding possibility, but maybe it'll change ;) .
