Documentation for the sculpt brushes seems to be a bit spare. In particular, I'm having trouble properly understanding the difference between flatten, polish, and smooth.
Also, hitting Shift seems to cause one of those to take effect when other brush types are selected. This is convenient but I'm not sure I'm always getting consistent results.
It would be nice to have all brush types and options properly described somewhere. I'm starting to learn the code base but I'm not far enough to really tell what the brushes actually do.
Thanks in advance.
