Plain-weave fabric material with thread bump

In your harnessBlender toolMIT

Build a woven cloth node material on UV coordinates: warp and weft threads that alternate over and under by cell parity, rounded thread profiles that drive bump and edge shading, two thread colours and Principled sheen. Use it for clothing, upholstery, flags and furniture.

Limits. Plain weave only; twill, satin and knits are not modelled. Threads are straight and evenly spaced with no fibre fuzz, slubs or irregularity. The pattern follows the UV map, so it needs reasonable UVs and aliases when threads are smaller than a pixel. Rendered here with Cycles CPU only. Verified in Blender 5.2.1; written for the 4.2 API.
