There are 3 different cylinders. One with 6 side, one with 12 , one with 24 sides and an example texture.

If you wanna make a fence, make sure the texture is seamless
on the x-axis. Rescale the texture to something like 512x512, 1024x1024 and set Properties: Renderer--->Transparency to 1.

Have fun. Stringgod.
