Sam Welker shows some techniques for modeling in Cinema 4D using the Brush Tool to modify objects with an organic flair without too much effort.

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

Sam shows his process for creating an organic low polygon landscape in Cinema 4D and uses the brush tool to modify simple shapes in Cinema essentially doing some basic sculpting. Sam notes that this technique will be cumbersome with large polygon meshes, and does not recommend it. However, if you need to create some organic forms really quickly, this technique is for you.
