干地上的水纹投光

提示词

在选定干燥铺地上呈现水波状投射光纹，铺装表面、接缝和高差保持可辨；明暗纹理属于照明，不形成水层、积水边界或真实水面倒影。

Show water-ripple-shaped projected light on the selected dry paving, keeping the surface, joints and level differences legible. Treat the bright and dark pattern as illumination rather than a water layer, puddle boundary or reflection on actual water.
