I've been trying to work out how to create a similar indentation effect in Illustrator. I'm fine with creating the shapes, rotating them around a circle (Rotate > 360/12 > copy)...
...but I'm struggling with creating the illusion of depth.
I've been experimenting with drop shadow, strokes, opacity and bevel/extrude but am missing the right combination of effects to replicate this light highlighting and dark shadowing. What are the tool options for this effect?
