Selecting parts of an object

“

- [Instructor] By default in Zbrush, models are 100% visible. Everything can be seen at the same time. However, there are times when you want to hide part of a model to make it easier to see another part, or maybe you want to make sure that whatever you're doing only affects one section and not another. Whatever the reason, selecting in ZBrush is a must-know feature. Let's learn how. So let's select the hand of this character so that everything else is hidden. So I'm going to hold down Control and Shift and then draw a box over the hand. And to make it even more isolated, we could turn on solo mode to hide all the other sub tools. Now we could hit F or click on frame to zoom in to the hand. And just to demonstrate how this works, you could do some sort of sculpting on the hand, for example. And then when we bring back the rest of the body by holding down Control + Shift and clicking in an open area, you'll notice that this effect only went up to what was visible and then everything else was unaffected. So usually you don't want to have an abrupt transition on your sculpting like this, so you want to watch out for those edges and to make sure that edits you do don't go right up to that edge unless that's what you want. So let's look at some other ways of selecting. I'm going to zoom out a little bit here. Let's hold down Control and Shift. And you can see by default we've got the select rectangle brush. So if we click on this, we're going to get a couple other options here. Now, the other select brush is select lasso, so let's pick this one. Now with this, we can make more complicated selections. So I'll just draw a selection around the head like this. Now, whatever is in green is what is going to remain selected. Now, what if we want to see the body but not the head? That's very easy to do. We can do that by holding Control + Shift and clicking and dragging in an open area, and as long as the selection doesn't actually go over any polygons, it will invert the selection. And again, remember you can restore visibility to everything by holding Control + Shift and clicking in an open area. Okay, so that's the basics of selecting. Remember the operation is done through the Control and Shift keys to select, Control + Shift + click and drag in an open area to invert, and Control + Shift + click once in an open area to bring everything back. You'll be using this a lot.
