MetaCalvin | Skin Detail Pass
Continuing development on my long-term MetaCalvin project.
This update focuses on establishing the first production-ready skin detail pass after weeks of experimentation with transferring high-frequency scan data into ZBrush. The workflow is now stable, allowing me to shift away from solving technical challenges and spend more time refining the artistic side of the character.

The skin surface combines projected pore information with hand-refined wrinkles, blemishes, scars, and subtle surface variation to avoid an overly uniform appearance. Rather than exaggerating the detail, the objective is to build believable layers that hold up to close inspection while remaining suitable for a real-time character.

A significant milestone in this pass was completing the 8K normal map baking pipeline, successfully transferring the sculpted information onto the game-ready mesh. This establishes a solid foundation for future texture refinement, tattoo integration, facial hair, and additional material work.

This post includes both still renders and a video showcase to highlight how the surface detail reacts under different lighting conditions.

Software used for this task was ZBrush for sculpting, Marmoset Toolbag for baking/lighting, Substance 3D Painter for refining texture passes, and Unreal Engine's MetaHuman Pipeline.
