Video: Understanding ZSub and ZCut

Now we're at the point in my illustration where I have decided that I want to add some details to my robot army. How would you go about doing that? Well, what you can do is you can actually use some of the 3D tools here as embellishments. Now the document that I have open is called robot_army_v01.ZBR. I have that loaded on to the canvas. What I want do, is I want to use Sphereinder3D tool to add a few bolts, but I also want to use it as a way to gouge some holes into the surface of the robots for additional details.

Pixologic's ZBrush 3 stands at the forefront of digital 3D sculpting and 2.5D painting, a new medium that is taking the art and entertainment worlds by storm. Visual effects artist Eric Keller shares his expertise and talents in ZBrush 3 for Windows Essential Training. He presents the concepts behind digital sculpting, shows how to produce fantastic images using the unique ZBrush toolset and interface, and demonstrates the power of the Digital Clay and Sculpting brushes. To offer a richer understanding of the application, Eric gives a guided tour of the interface and addresses the most common problems experienced by new users. Exercise files accompany the course.

Topics include:
  • Building and posing digital armatures for sculpture
  • Importing models from other 3D programs
  • Learning how to sculpt a human head based on reference images
  • Detailing skin and surfaces using textures and stencils
  • Creating illustrations with depth, lighting, and surface materials

Understanding ZSub and ZCut

Now we're at the point in my illustration where I have decided that I want to add some details to my robot army. How would you go about doing that? Well, what you can do is you can actually use some of the 3D tools here as embellishments. Now the document that I have open is called robot_army_v01.ZBR. I have that loaded on to the canvas. What I want do, is I want to use Sphereinder3D tool to add a few bolts, but I also want to use it as a way to gouge some holes into the surface of the robots for additional details.

So the way we do this is to use the tool in either, Z Add, Z Sub, or Z Cut mode. When I'm in Z Add mode, and I draw on the robot, we see the sphere tool is actually added to the surface, just click Undo to get rid of that one. So I'm adding bolts to the surface of the robots here. Each time I draw a new bolt, the previous bolt has been dropped to the canvas, it has been converted to pixels. So now it's part of the canvas, but until I draw another bolt, I still have the opportunity to reposition the last one that I drew. So in other words, if I don't like where that was, I can click on the Move button, and that activates the Transform Gyro, and then I can use it to position scale or rotate this bolt.

Switch back to Draw mode, I can draw some more bolts. When I draw these bolts, they automatically come out perpendicular to the surface of the robot. So if I decide that I want to gouge a hole into the robots armor, or any of the pixels on the canvas, I have two ways the do this. I can use Z Sub, or Z Subtract, and Z Cut. Now the difference between these two modes, is a little bit subtle. If I'm in Z Sub and I draw a Sphereinder, a special type of cylinder, you can see that I'm cutting a hole into the robot. I'm going to rotate this hole that I have cut in there, and you can see the edge of the Sphereinder. Let's move it up a little bit, there we go, and rotate, so you can see that bottom edge there.

So when I'm using Z Cut, it's like I'm projecting from the front of the canvas into the robot to gouge out that hole. If I switch to Z Cut, as oppose to Z Sub, you can see the difference there. It's a little bit subtle. So let's rotate a little bit more, and when we position this deeper, let's scale it out a bit. Let's switch between the two, that's a little bit more obvious, and I have got a second, always zoom in on the canvas to get a closer look.

So Z Sub is projecting that hole from my point of view, and gouging into the surface. Z Cut is more like a 3D hole; it's like the Sphereinder tool, is a drill, that's drilling into the surfaces. Now when you might want to use one as opposed to the other, it depends on what you are trying to create, what kind of detailing. Let's rotate this guy a little bit more. Maybe he has got canon balls shot at him. You can switch between these two, see how that might be useful.

If I wanted to create a detail like, he has just got this open area in here that you can see into, Z Subtract might be better than Z Cut, but if I wanted to have like a hole, like so he has just has been drilled down, like some kind of advanced laser weapon technology coming for the satellite, it's possible I'm thinking about this too much, but you get the basic idea that actually cuts into the surface, as opposed to gouging out, or subtracting from the surface.
