Create a highly realistic 3D model of a knitted beanie hat with a military-style camouflage pattern. The beanie should have a soft, folded brim with visible woven fabric detail and a leather patch logo embossed on the front. The camouflage texture is a blend of green, brown, beige, and dark red, with subtle distressed and worn effects. Fabric fibers and weave pattern should be clearly visible in 8K UHD PBR base texture. The shape is slightly loose and natural, as if resting on a head. Use realistic fabric roughness, normal and displacement maps. Optimized UVs, clean topology, suitable for AAA games or cinematic renders. Output formats: FBX, OBJ, GLB, STL.
