Join Ryan Kittleson for an in-depth discussion in this video Introducing Gizmo 3D, part of ZBrush 4R8 New Features.
- [Instructor] The latest update to ZBrush includes a long-yearned for 3D Gizmo. Now pretty much every other 3D software has had one of these babies since the 90s, and now we can welcome ZBrush into the 21st century. If you have ever used any other 3D software, the Gizmo will be immediately intuitive. However, there's a few interesting things that ZBrush does differently, so let's take a look at it. Okay, we've got any old file opened, it doesn't really matter what it is. And you get into the Gizmo the same way you used to get into the Transpose Manipulator, by going up to Move, Scale, Rotate, or hitting W, E, R on your keyboard.
For the most part, the Gizmo is easier to use and more powerful than the old Transpose Manipulator, but you can still access it by hitting the Y key, or clicking the Gizmo toggle. Okay, let's get back to the Gizmo. So we'll turn the toggle back on. Now it should be pretty obvious how to move, scale, and rotate objects with the Gizmo. You just grab on them with any of these manipulators to move them, you can scale them in any particular direction, I'll hit Control + Z to undo that. You can scale the entire object at once with the center yellow box here.
You can move according to the screen space by clicking on any of these corners here. You can rotate in the screen space by clicking and dragging on the white circle. I'll just hit Control + Z to undo that. And of course you can rotate in any of these particular directions just by clicking and dragging on these colored circles. Pretty straightforward, pretty standard to any 3D software. Let me hit Control + Z a few times just to go back to where this was before, okay. A couple of interesting things you can also do with this is, you can scale on a single axis of course like we just tried here, by clicking and dragging on the rectangles, just undo that.
But you can also scale in the two axes that are other than the one you click on by holding down Alt as you click and drag on it. So let's just see what that does. So you can see, it's not scaling forward or backward at all, but it's scaling left and right, and up and down. So that's kind of an interesting effect. We'll just undo that. You can also move the manipulator without moving the object by holding down Alt. So this way, we can move the manipulator, and say you want to rotate from a different position, now you can just do that with the manipulator in a different location, and it creates the pivot point wherever the manipulator is.
So I'll just undo that. Now there's a couple of controls here above the Gizmo. Let's look at Pin, or Sticky Mode. So with this turned on, what happens is if you move the manipulator, the Gizmo will actually snap back to where it was before. This is if you want to keep the Gizmo in the same place all the time, you can just move the object, but the Gizmo stays in the same place. I'll just undo that. Go ahead and turn off Sticky Mode for right now. Now, something else you can do is, let's say you've got your Gizmo and it's kind of moved off center, and you want to return it back to the center of the object.
For that, just simply click on this little icon right here, and that sends it to the unmasked center. So this is kind of interesting. Let's actually undo that. And let's mask off most of this model except kind of the front end here. Now let's see what happens when we click that. So this time, it goes right to the center of whatever's unmasked. Okay, we'll just go ahead and undo that. Now the home button will move the model, or the Gizmo, to the center of the scene. So if we click on that, everything moves to the center.
If we hit Control + Z to undo this, and let's do this a different way. If we hold down Alt, it just sends the Gizmo without the model to the center of the scene. Now let's go ahead and rotate this in a couple of different directions to try out the next feature. Let's just say your model's kind of oriented strangely like this. If we hit the reset orientation button, what it does is it just moves everything back to orthogonal with the grid. So, it moves the Gizmo back so everything is facing in the cardinal directions. If I hit Control + Z, and hold down Alt while I click on this, what it does is it just repositions the Gizmo with the grid, but it leaves the model where it was.
Okay, there's a few other features, but they get a bit more in-depth, so I'll cover them in the next few videos. For now, feel free to play around with the Gizmo, and get a sense for how it works.
