LineRenderer.textureMode

Descripción

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

Stretching will cause the texture to be mapped once along the entire length of the line, whereas Tiling will cause the texture to be repeated at a rate of once per world unit. To set the tiling rate, use Material.SetTextureScale.
