In this tutorial I show you how to use the brush tool in R13. This tool is incredibly useful for quick modeling and should work as far back as at least r12. This is not sculpting and will not work with huge poly counts nearly as well as sculpting does however it is a little similar in usage and quite the tool you should all be using.
I wish I had known about this tool when I was starting out so I decided to make a quick tutorial on how to use it.
