Any way to tune color change seams? (See photos)


I want the white pieces to be more precise at printing, as you see, it creates really ulgy seams withing the eyes!

I also need to know how to select the color (filament) for the seams.
On many models the seams are using a “Default” material which I have found no way to define. In my case that defaults to the material loaded into AMS slot 1 and thus introduces many unwanted filament changes.
