Question 4 directions Rig & Sprite Swap

Hello together
I'm currently working on a game in that I want to represent the characters in 4 directions

My knowledge
I have so far studied the Unity manuals as well as gone through various tutorials, however I have not found a workflow that is made for 4 directions of character.
https://docs.unity3d.com/Packages/c...9.0/manual/ex-sprite-swap.html#full-skin-swap

Objective

• Import character man and woman in 4 directions
• Skinning editor (would like to work with bones)
• Sprite Libary (Part Sprite Swap)

The man can choose different hairstyles and eyes, but not the same as the woman. I assume that this is done with different sprite libaries?

Sprite Libary

• How should I build the sprite libarys if I want to do the part swap (man and woman have the same skeleton, skeleton sharing)?
• The character should also be able to carry items in both hands, how do I do that best, does that affect the skeleton?

My PSB files are organized like this so far:
I created a PSB file for each direction (Man as well as Woman are separated:

• Man_down, Man_R, Man_Up, Man_L
• Women_down, Women_R, Women_Up, Women_L

Here the individual layers are visible:

• Eye_R, Eye_L, Head, Torso, Arm_R, Arm_L, Hand_R, Hand_L, Leg_R, Leg_L.

I am totally lost, have a mess in my head.... I would be really happy if you could help me.

Thanks a lot
