Finetextured

Finetextured is a descriptive term used in computer graphics and material design to denote surface textures that exhibit fine, high-frequency detail at small spatial scales. It contrasts with coarser textures and is applied to materials intended to look smooth from a distance while revealing intricate grain, pattern, or irregularities upon close inspection. The concept is used to communicate a desired perceptual effect rather than to denote a formal technical standard.

In rendering workflows, finetextured surfaces are usually produced by layering multiple texture channels. A base color (albedo) map provides broad coloration, while a high-frequency detail texture or microtexture adds fine variation. A normal or bump map encodes small-scale geometric direction changes to affect lighting, and a displacement map may be used to alter geometry for near-camera views. Microfacet-based lighting models can help reproduce the subtle, sparkling highlights that arise from fine surface irregularities.

Common examples of finetextured materials include silk, satin, fine wood grain, brushed metal, denim, parchment, and skin with pores or micro-skin details. Creation approaches combine procedural generation with photographic sources: procedural noise and fractal textures can create repeatable fine detail, while real-world textures captured through photography or photogrammetry provide authentic microfeatures. Techniques such as tiling with seamless textures, detail layering, and multi-scale sampling are often employed to maintain realism across viewing distances.

Considerations for finetextured work include balancing memory usage, avoiding aliasing or moiré at high frequencies, and ensuring proper sampling across mipmaps and anisotropic filtering. The term remains a descriptive label rather than a formal standard, used by artists and developers to convey the intended perceptual quality of tiny surface details.
