Hi Jeremiah, i’m trying this out, it’s super interesting. For a project I’m trying to create a control rig for a face. The character is 3D but the face assets are set up in a material through which you can animate it using the material parameters. This can be used in the sequencer but I’m hoping to be able to create a control rig with it. So far i got 1 of the parameters to work using the steps you showed. However I am struggling with another which in the material is set up as a vector 3 (or 4?) and uses the red and green channels to move the pupils around. But i feel like i can’t access those this way. Do you have any tips on how to access the channels in the control rig as well?
