Join Henry Santos for an in-depth discussion in this video Utilizing locators, part of MODO Essential Training.
- [Narrator] Now that we got a view of the basics of rigging, or what a basic rig looks like, let's go into how we can make that process a little bit more predictable, and a lot more useful for what we want to do. So where we modified this actual mesh, by rotating it, and setting up the center point, we tend not to use that in rigging world. We actually would prefer to animate, or put animations, on what are called locators.
We try not to do any animations or set animations on the mesh's themselves. So let's bring up a locator here. In the top, left, corner of our screen we have these different options. We have this star shaped thing, and then all these other guys, and then there are rotation controls and modifying controls. That top left corner, that's the locator. So let's click on that, and that brings in that locator. It's kind of giant, but let's shrink that down.
I am going to the properties on the right side of our screen. So right now that locator is selected. Let's see how this is displayed. I'm gonna hit display options on the right side of our screen. Right now it says size is one. Let's click on the slider icon here, so we can change that size so it's a little bit more manageable, and we'll take a look at other ways we can display that. Right, so we need to position this. So, again, I'm selecting that locator, let's position it in the center of that base, but it's kinda hard to position that exactly in the center, so let's move that out.
And in Modo we have a quick feature, where we can drop this on top, so we can drag and drop it on top of the item, and it places it right in the center. So it borrows that center and it locates it there. So if you go to the very top of the screen right above our view port, we have drop actions. So let's click on that and bring that option down, and we can select match position. So let's match that position, and now if we click and drag on that locator, there it is.
Right in the center. So let's take a look at this view port, let's change it to a perspective view. So front, I'm gonna go to the top left corner of the view port. I'm gonna click on front and perspective. Now we can navigate around and see kinda where it is. Okay, so that is where the center is. Perfect. So, instead of modifying any of these mesh's, what we can do is modify the locator and place the mesh as a child of that locator.
Remember that parent, child thing? So I'm selecting this locator. Let's try to rotate it. Sure enough, it rotates. And if you look at the properties in the properties panel, the rotation Z changes as well. So let's get back to 0.0, and because this has been positioned on there, it shares the same space, so it went to the center point of this clock base, but if I click on the clock base and move it, the locator stays where it is, because it's not really a child of that clock base.
So let's undo that clock base move, and I'm gonna drop the move tool so I don't accidentally move it somewhere like I just did. But under the drop actions, we have an option for Parent in Place, so if we select that, now we click and drag that locator to that clock base, and we activate that drop action, and let's move this clock base around.
Sure enough, it is now a child of the clock base. The locator is a child. So, if you rotate this again, there's still nothing connected to it, but it's at the right center point. So let's select the Bar_Hour, that geometry there, and let's look at the item list, and look at Bar_Hour, and notice that there are children underneath that, so the clock face of the hour, right there, that has always been a child of the Bar_Hour, so it's gonna move along with it, but we wanna make that Bar_Hour, since it's the parent of that face, we wanna make that the child of the locator.
It is a lot of things going on here, so stay with me here. So, drop action is set to Parent in Place. That's what we want. Let's click and drag that hour bar and put it on the locator. So now let's rotate that locator. There it is. So these are very basic rigs, basic setups, we're not doing anything in the schematic view, and now, this is much easier to animate. But, the view of that locator is not that appealing, especially if you have multiple locators.
Add another one, and then another one, and we'll move that. So it just gets really cluttered, really fast. So undo, make sure that still works. So, we're gonna change the display of that locator, just like I said earlier. Let's go back to our locator properties, and not necessarily in display, but under shape within the properties, in locator properties, shape, it's set to default, so it's at default jax looking thing.
Now we have a giant cube, because the default setting for the custom shape is a box. So I clicked on this double right-facing arrow to look at the options below, and you have the style is replacing that original default shape, and the shape is set to a box. So if you wanna keep that box, let's see how we can shrink it. Let's go down to the size. I'm gonna you beat gang change here, so that it changes all of these values at the same time.
I'm gonna click on the left and right sliders to the right of that, and shrink it down so that we have a box. Looking better, but let's look at different options. So the shape is a box, let's change this to a circle. Yeah, that looks better. Change the radius, going down to the radius option here. But we don't need it solid. We don't need it filled in. So there's that ring.
That is awesome. So now, if I select that ring, and hit rotate, what I'm doing is selecting the locator, and then I can place my animations on that locator and not the mesh, and that is a much better work flow for what we wanna do, and the animators will be happy. So, the last thing I wanna show you with this locator, is when you select it, you can also change the color, and that goes back to display.
While we have the locator selected, we go to our properties, and go to the display options, then we can add draw options, and here we can change the wire frame color from default to a user color. So we're gonna change that to user so we can specify that, and we'll use that blue, to keep it all color coordinated. There we have a blue ring that controls the blue object. So you can continue on with this, and create a locator that is for the minute hand and the second hand.
So as we've seen here, locators become very, very useful tools. There are also very specialized locators, called, skeletons, that we'll take a look at in the later video.
