LipService

LipService is a powerful multi-resolution subdivision surface sculpting
and animation system built into a single 3DSMax object modifier.
LipService's sculpting tools are comparable to ZBrush and Mudbox. Its
animation tools extend this multi-resultion editing philosophy through to
motion.
LipService makes facial animation fast, simple, and gives the artist full
WSIWYG control over the whole process.

LipService is a powerful extension to 3DSMax, not an external window, but
an object space modifier. The artist keeps their favorite hotkeys,
preferences, and menu paradigm. If the artist knows Max, they will
immediately be able to use the tool without even cracking a manual. If
they're used to sculpting with ZBrush or Mudbox already, they will find
the sculpting tools and workflow familiar.
