blue fiber mesh 3d model

Ultra realistic nonwoven continuous filament fleece made entirely from thousands of ultra-thin tangled blue polypropylene fibers, long rectangular slab stretched along X-axis, thin height on Z-axis, porous breathable structure with visible air gaps, tunnels, and open pore channels throughout the entire volume. Only curved cylindrical fibers should exist, no solid core, no cloth surface, no foam, no blobs, no extra geometry. Fibers are randomly twisted, overlapping, intersecting, and layered in chaotic organic patterns like industrial melt-spun agricultural fleece material. Thin smooth microfiber strands with subtle thickness variation, spline-like curves, procedural geometry nodes style generation, airy lightweight structure, high airflow permeability. Matte synthetic texture, soft diffuse reflections, realistic ambient occlusion, deep internal visibility through gaps, photorealistic CGI, Blender Cycles or Octane render style, dark studio background, cinematic lighting, sharp focus, 8k
