I am using Zbrush 2021 to sculpt a skull using 2 different skull reference images in the same view.
The goal is to create another skull that is based on both references.
I need to refer to both references back and forth varying the translucency of the front image.
Ideally it would be best to lock the geometry to the Grid(?)so when I move my model the reference images are locked in place with the model. What is the best way to accomplish this?
