MotionBuilder: Essentials Characterization, Retargeting and Baking Animations

How to read this

Category

Production talk / tutorial (MotionBuilder essentials)

Contributions

• Explains what characterization is and how to characterize a Mixamo character (biped vs quadruped) so it can be driven by mocap, a control rig, or retargeted animation
• Covers importing in T-pose via FBX merge, grouping skeleton and mesh, dropping the template on the hips, and validating automatic bone mapping
• Shows retargeting a walk by setting the source skeleton as the character source, looping via match, and baking by plotting to the target skeleton

Context

Companion essentials walkthrough to other MotionBuilder retargeting tutorials (e.g. How to Retarget Motion Capture in MotionBuilder, 2019), grounded in the same HumanIK characterization workflow.Builds on: How to Retarget Motion Capture in MotionBuilder

Correctness

Studio/tool practice, not peer-reviewed; production-proven but tied to MotionBuilder HumanIK and to a clean T-pose with correctly named bones (notably the biped vs quadruped distinction).

Clarity

Beginner-friendly and accessible; one pass conveys the essentials, with replay value at the characterization and baking steps.

How to read it

Watch hands-on; pay attention to the biped versus quadruped choice and the plot-to-skeleton bake, and treat it as the entry point before the more advanced characterization tutorial.
