📋 About This Mod
This mod add clothes to look like synth for any npc, settlers, the player, ghouls,...
The synth models are mashup: legs, chest, arms, hands, heads, mask, googles, full body, eyes.
Models: original creation, from my other mods or made from Fo4 models. (male and female versions)
Armors have lining, legendary, HUD target, radiation resist....
Bodyslide files for female models.
"West Tek Tactical Optics" Patch to add/replace the Vision Effects (night vision, thermal,...) for eyes and googles.
If you wanna turn player voice like a synth try this mod: Synth Voice Player Simple
Fullbody synth have merged legs, arms and chest in 1 model to save slots (dont use legs or arms whit it).
The clothes need slots to be displayed, if you wanna use clothes from another mod (mashup recommanded) may be you need to change the slots to avoid conflict, use the creation kit or Fo4edit (full body use only the slot 33 to free more slots).
know issue due to limitation of the game:
Arms and legs synth must be used whit chest synth (in default body arms, chest and legs are in 1 piece).
Use the 2 hands to avoid hand invisible (in main game the 2 hands are linked).
In 1st person the game use only slot 33,34,35 (hands and body) then the forearms display are the forearms of the chest equiped.
Synth heads are not animated (face anims are link to the npc id not in wearing parts).
I do not find a way to modulate the voice when synth head are wearing... (if you know how let me know)
