Across the surface, the sand shows fine wind-ripple detail—thin, parallel micro-grooves that become more noticeable where the light strikes at an angle and fade gradually with distance. The material looks matte and dry, with high roughness and very soft highlights, so it doesn’t feel glossy or wet; instead it has a natural, muted response to light where shadows are smooth and the ripple normals add a mild grain without visual noise.
