Seamless tileable texture
of [material]. Even light,
no directional shadow,
no visible seam at any
edge, uniform scale so
it repeats cleanly.

Seamless Repeating Texture

A texture that tiles invisibly, which mostly means getting the lighting flat.

Prompt

Generate a seamless, tileable texture of [material — cracked terracotta, brushed steel, woven linen]. Even lighting with no directional shadow, no visible seam at any edge, uniform scale across the whole square so it repeats without an obvious motif.
