I can change the display mode of the eyes but can’t seam to change the display mode of the head
It’s really annoying, If I wan’t to see how the material is doing I must go in rendered.
there isnt really any good preview for cycles, you have to render.
i think what your looking for is under settings in the material tab. right under the displacment section. that will let you change the way it looks in the simple viewport solid mode.
