Denim is one of the most technically complex materials to render digitally. Unlike simpler fabrics, denim exists across hundreds of variations, each with its own wash, weight, weave structure, surface texture, and finish. From raw selvage to heavily distressed, from deep indigo to bleached white, from rigid 100% cotton to blends incorporating elastane, Tencel, or polyester, every combination creates a unique visual and physical identity that is notoriously difficult to reproduce accurately in 3D or AI-generated environments.
