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.
