1. Muscle IDs from Path Attribute

Building on a concept covered previously of using an existing name attribute to create a muscle_id attribute, we show you how you can extract the muscle_id value from a part of a longer attribute value. A typical attribute that you would use for this, the path attribute, stores the hierarchy of the geometry pieces when importing an alembic or USD file. We show how to extract the value with VEX, as well as with an Attribute String Edit node for those overwhelmed by VEX, although we walk you through the very simple VEX code so give it a try!

Nice to see SideFx are releasing more tutorials for muscles.
We need more tutorials, including for tissue and skin, and how to use it in a work environment
