This mod is a creation by molerats. I am merely porting it.
From the Nexus :
Remodel of synth armor to make it look more protective and higher quality.
Summary:
Synth armor now looks protective and has more of a distinct style
Sharpened edges / lines of model to indicate quality production
Helmet redesign giving the normal one extended face glass and the field version the light/scanner thing too. Extra model redesign for them as well
Custom ground / Pip-Boy models were made to reflect the new changes
Texture compatibility:
Should be compatible with any synth armor retexture
See screenshots for example using AS Synth Armor Redone
C.A.S.T. should be compatible but I’m not sure if the helmet changes will transfer
