UltimateSkin is a procedural skin shader designed for both EEVEE and Cycles. It provides a highly customizable node group for generating skin details, supporting both image texture inputs for existing projects and a non-destructive mask-based workflow for new setups. The shader includes dedicated parameters for generating cells, pores, blemishes, freckles, veins, moles, red spots, goosebumps, and pimples.
