LineRenderer.textureMode

Description

Choose whether the U coordinate of the line texture is tiled or stretched.

Stretching maps the texture along the line with no repeats. Tiling maps the texture along the line with repeats every world unit. To change the repeat rate, use LineRenderer.textureScale or Material.SetTextureScale.
