Stuck on making custom Protectron

[Zorkaz]

I already have made a custom texture/material file for a unique protectron.

 

But I'm unable to give the protectron a unique skin. Where do I set this?

My guess is Object Template, under Traits tab of the NPC form. I see Bethesda added Object Modification with material swap there. I haven't done something like this myself, take a look at:

Protectron_Medic [MSWP:001B19CB]

Bot_Mod_Property_MedicWhite [OMOD:001B312C]

EncProtectronMedic01 "Protectron" [NPC_:001E61E3]
