Likeness of actress Lupita Nyong'o done during the Likeness Course at ArtHeroes.
This was a huge challenge for me but incredibly fun to produce! Huge props to the whole ArtHeroes team for assembling such a smooth workflow for CG likeness creation.

Microdetails were achieved with a mix of XYZ maps and hand-sculpted details. The texture is a mixture of polypaint and Ten24 scanstore maps. Rendered in Marmoset Toolbag 4 using the new raytrace feature.
