Anzovin Rig Nodes (or ARN) is a freely distributed plug-in for Maya that will supply you with all the custom rigging nodes we’ve written at Anzovin Studio for use with our own rigging tools. ARN allows you to animate with a rig built with The Face Machine even if you don’t already own TFM.
What this means is that only the animator or TD creating a rig needs to have a licensed copy of our rigging products while ANY animator who wishes to use the rig for animation only needs a copy of ARN.
TSM rigs currently use only native Maya nodes and do not require Anzovin Rig Nodes.
