Maya Skeleton Control design series textbook Two

Next we have to set the spine section, first of all to make two square curve controller to facilitate our operation. and move their pivot point to the top position. (You will know when you see the following actions)

(Fig 1 Square curve Controller)

Make a group of a curved line and become a sub object of the following curve.

(Figure 2 Top curve Group)

The bottom of the two clusters into a group of the crotch of the root control curve of the child objects.

(Figure 3 The bottom two groups)

After the last third cluster, it becomes the sub object of a control curve (BACKCONTRAL1) below the waist.

(Figure 4 penultimate cluster)

After the last two clusters into groups, the waist Below a control curve (BACKCONTRAL2) of the child objects.

(Figure 5 last two clusters in groups)

Well, we can control it now.

(Figure 6 complete)

Now you can see that we control the curvature of the spine by rotating the cluster. But the cluster is a point, so we can control it after it becomes a child object of the control object. The principle is simple, but with a simple example we can carry out more advanced, richer control that is our goal and the desired effect of this part of the tutorial.

So let's do a simple extension, we just need to rotate, so we just have to control the direction. Direction constraint is a good choice, we just have to put the original parent-child relationship.

It's better to replace it with a direction constraint. We need to unparent a group of two clusters first.

(Figure 7 replaces the direction constraint)

Select the lower control line, select the group in which the control cluster is located, and execute the direction constraint.

(Figure 8 Execution direction constraint)

Select the control line on top, then select the group in which the controlled cluster is located, and execute the direction constraint.

(Figure 9 Execution direction constraint)

It then makes a parent-child relationship based on the relationship between the cluster and the control line.

(Figure 10 A parent-child relationship)

Now turn the control line. How can it be so strange??

(Figure 11 Turn control line)

The reason is simply that the axis of the parent's child object can be said to be gone, and the direction constraint is rotated by the original axis of the object. It's a good idea to do that. We can move the axis of a group of two clusters to roughly the same position as the previous control line axis. (Now you know where to move.)

(Figure 12 Reason)

What's up, it's done. In fact, a lot of advanced control is a simple control derived. Knowing the ideas and methods we can do a lot of very complicated things.
