Woven fabric with thread relief and sheen

In your harnessGodot shaderMIT

Woven cloth from UVs: warp and weft threads crossing over and under in a plain or twill pattern, each thread shaded as a rounded strand through the normal map, with Godot's rim term for the soft cloth sheen.

The render its check recorded in Godot 4.7.2, 256 by 256 pixels.

What it takes and gives

Shader type
spatial
Render modes
cull_disabled
Parameters
warp_color (vec4 = 0.22, 0.32, 0.55, 1), weft_color (vec4 = 0.75, 0.72, 0.65, 1), threads (float = 60), twill (bool = yes), thread_gap (float = 0.12), relief (float = 0.6), fuzz (float = 0.25), sheen (float = 0.6)
Use it on
A mesh with UVs and tangents; thread size follows the UV scale.
Result
A blue and cream twill cloth with visible rounded threads and diagonal ribs.

Limits. Threads alias into moire when they get smaller than a few pixels; lower threads for distant cloth. Relief is a normal map only. The rim sheen depends on renderer support for the RIM output.
