Here are my work for the non playable character that you can find at Lumiere.
First of all I was not alone in the process.
Ophelie Gomez made the outfit
Alan also made outfit (expeditionner's one mainly) and resculpt some faces to level up those NPCs.
Armande made the hard work alonside Alexandre to do the VAT version of those NPCs.
For my part I made the Face, implemnted it.
Optimise metahuman shader, paking texture, baking groom to add them in texture.
And of course some Haircut.
Still I did reuse many things from metahuman.
