16/03: UV Mapping

I’m going over UV mapping which is basically about taking the skin of a three dimensional model and ‘mapping’ it out into a two dimensional plane so that you can add a texture or image to the 2d plane. It’s like taking a 3d box and opening it out into its two dimensional counterpart, as shown below.*

*There is no texture added to the UV map in this diagram

Although it looks pretty straightforward, which it is with a box, it becomes increasingly difficult the more lines you add to the model. Imagine what the UV map of a human would look like. or a dragon. The more intricate the model, the more difficult it becomes to UV map. In fact, to do this well, it becomes difficult to do this on even the most basic of models, like in class today.

I was given the task of UV mapping a barrel, which while I had some success with, proved to be more difficult than I would imagine.

Unfortunately, Maya wasn’t playing ball with me today and would crash when I added the texture to the UV map. Because of this I was unable to get a finished product to screenshot. However, I have taken this image from a guide I was following and this is what a textured UV map would look like:

As you can see, you would take the barrel model and unfold it into its 2d counter part, apply the different textures to the corresponding parts, and then that textured UV map will project onto the 3d model in Maya.
