Pack features 78 head scans, 36 male and 42 female models. These head scans were captured using our specialized 120-camera rig, resulting in high-definition detail. The model has been meticulously cleaned and processed to create a production-ready mesh, capable of withstanding extreme close-ups while maintaining sub-pore level details in both texture and geometry. Additionally, we've included the source ZBrush files, allowing you to export your own maps or use the scan as a foundation for another character. The dataset also comes with a Marmoset Toolbag 4 scene.
