Let's explore how easy it is to create characters with ZSketch. For me, this is one of the best features of ZBrush because it brings modeling closer to what sketching is — quick and intuitive. Let's see how this works by sketching out the creature's body. The hair will be added separately in the next chapter, so we'll now focus on the muscles:
1. Open or select the previously built armature.
2. Go to Tool | ZSketch and press the EditSketch button or hit Shift + A. Now we're in Sketch mode where we can sketch freely upon our armature.
3. Make sure that Symmetry is active.
4. Pick a material that starts with Sketch, which were especially designed to enhance the display of ZSketches. I'm using SketchShaded4 here.
5. ZBrush automatically switches to the Sketch1 brush when working with ZSpheres so we can start right away. The next image shows how we can lay strokes onto our armature and smoothen them afterwards to blend into the existing sketch...
