Have a custom model of a singing Christmas tree (8 AC channels). The model I am using has 9 channels with the difference being that the model I am using uses a left and right eye but I use an open eye. How do I modify the custom model to reflect 8 channels? I have spaced out one of the eyes and changed the other to say Open Eye. Shouldn't these show up on the strand side and not node given I am using AC?
