I was responsible for creating the head of Martinez' Assistant in the Colombia level. This head was based on concept art by Anders Poulsen and photographic references. It was modeled in ZBrush by adding features on layers to a base head in order to iterate non-destructively. Details were added by using a combination of sculpting, scan and XYZ maps. The skin is generated and further worked on in Substance Painter.
All models are real-time rendered in-game. The haircut is hand-placed in Maya by me and specially fitted to her head since it has a unique skull shape and a characteristic haircut. It consists of around 8k tris.
