Tuck Brush

A Zbrush brush preset useful for tucking and sliding sides of the mesh into itself, leaving the front faces intact.

I tweeted out the settings for this on twitter, but realized it might be best to just share the brush, already correctly set up.

Drop this file into your ZStartup/BrushPresets folder, and look for it in Zbrush under the hotkey combo B+T (mine shows up as B+T+M but I think the exact hotkey combo depends on other brush names you have)
