Digital Tutors - Utilizing the Auto Rig and Muscle System Tools in Houdini

Duration 4h 14m Level Intermediate Project Files Included MP4

Throughout these lessons, we will rig up a character from scratch using Houdini's Auto Rig and Muscle System

tools.

In this tutorial, we begin by importing the cage meshes and assigning materials. Then, we will create the Auto

Rig system, paint influences, add facial blend shapes, and rig up parented eyeballs.

By the end of this training, we will also go over a quick lighting setup and tweak materials as well.
