Transparent Textures

How can i make a transparent texture? i still havent figured this out, and i need to make a fence. Please help!

You need to create an image that has an alpha/transparency channel. Find out how to do this in your favourite image editing program.

Once you have imported the image into your Unity project, simple click on the images material and choose a Transparent or a Cutout shader instead of the Diffuse shader that is usually the default one selected.
