After many hours of fun playing with materials for my 11 systems of the body project I come up with loads, and have 10 of my best materials that were the end result of the experimenting, that will be used for the various purposes that I made them. My favourite is the sketch material. The sketch material can be adjusted to look like a thin pen line, thick pen-line, or whatever you like. It is best used with a 3d plane behind it with the same material applied if you use it exactly as I have uploaded on here. You can put a pen or sketch filter over the top if you choose within Photoshop to get more of an effect. the example shown below is straight out of Zbrush (dont apply a shadow with sketch for normal usage). Maybe if you make any variations of these materials you could post examples on hear and also share the materials you come up with.
