Sub-Surface Scattering (SSS)

Light penetration through skin / wax / marble — essential for photoreal humans.

Sub-surface scattering simulates light penetrating below a surface (skin, wax, marble) and re-emerging diffusely — essential for photoreal humans where skin reads as living tissue rather than plastic. EquipVerse Cinema-grade skin shaders include dual-spec SSS plus eye caustics for theatrical-grade close-ups.
