Little question with ART V1.0

Hello! Just a little question about rigging with ART.

I’m aware that currently there’s no facial rig for ART, so I plan to build my own facial rig and attach it to ART’s rig.

But as far as I’m trying right now. The controller I’ve made for the bone in the ART’s editor doesn’t work. The transform and rotate controls are locked. It was even hidden because I parented the control in the ART’s rig (which when imported is hidden by default).

I could make the question even longer than this, but I just needed the general idea on how to attach my own rig to the ART’s rig. Especially for this kind of rig, which has loads of control and constraints.

Thank you!
