The blue guy: When you start a new project, select the “Third Person” template. Make sure you have “with starter content” as well.
For the second uv channel you create this inside your modeling package. If you are using max, you apply an unwrap modifer. Set the channel to 2, and click “abandoned”. Then you can just use a simple Mapping -> flatten mapping. Try a spacing variation between 0.01 and 0,007. That should get you started.
