Group tutorial: UV mapping

Technically, this isn't a tutorial, but just something I've learned while trying to texture the cacti for our game, Boulderdash.  It works out better if one adjusts the points into a rectangular figure and adjust as per the geometry.  Unfortunately, Unity cannot make UV maps in program, so working in Maya and then rendering (it doesn't show how the texture will work on the UV mapping editor) [Turns out setting the renderer to Viewport 2.0 fixes this.  Never mind.] is the only way I can do this.
