3D Character Rigging Timelapse - Part 4, Face and Lips

Here's the fourth part of my full character rigging process, showing the base of the face rig and the lips.
Most of the techniques used here have been covered in previous tutorials, but since I often rework my methods, some could be a bit different.

This part took me 4.5 hours to complete. Hopefully the timelapse can give you some clues and ideas and be helpful to some of you.

it's so interesting and informative watching your tutorials and seeing your process through these timelapses! thanks for sharing them :)

it's also really great motivation to learn python because seeing the transformation constraint process simplified so much through the addon you made is really cool. keep up the great work!

Your style of making models is so neat! It gives me motivation to *try * and make my own models too! :)

That's awesome! I'm working on a short animated film, and this is really helpful.

after applying stretch to constraint child bone gets rotate
How can we avoid that?
Can you please make any tutorial for explain how to handle bandy bones accurately.

[proha_show]

please help! what is the addon where is the title 'transfer to transformation constraints'? you used it to set bone's poses dependences
