Part 2:
Planning and Laying out the Bones

The next step is where we draw a bunch of bones all over and across the leg, typically from its 'anchor' point by the hip, down through the knee, into the heel and to the toe.

Here's roughly what we'll draw. One bone from the top to the knee. The second bone from below the knee to the ankle above the foot, then another into the foot, etc... all the way to the toe.

In fact you could make it much simpler. But this will help if we want more detailed posing controls.

Here we go:

Click the Bone object (B) in the tools collection. Click the Lathe tool and drag down to select the Bone tool.
Move the cursor into the top of the leg and start drawing down.
Stop right above the knee. Don't worry if the drawn line is not a perfectly straight line. It doesn't matter. This is not the bone, just a way to tell the system where the bone starts and where it ends.

Release the button.
As soon as you release the tablet or mouse button, a straight line is show, with a color gradient from orange at the start to white at the end. That is the bone.

If you hit SPACEBAR, you're done with this bone.

However, let's draw one or two more curves...
Draw one curve around the start of the bone, to show the extent of the bone's reach, i.e. the size (diameter) of the influence sphere.

As soon as you've finished drawing that second curve, you'll see the newly sized spheres of influence. Both are the same size.

If you want the lower (end) of the bone to show a smaller sphere of influence, just draw another curve down there.

Just liek this. Now there are two lines controlling the size of the spheres: one at the top, a second at the bottom.

And there it is. Now the bone has two differently sized spheres of influence, better suited for the changing size of the leg.

Hits SPACEBAR, and you're done. The bone remains visible, the construction curves are hidden (but not lost), and so are the spheres.

We can now draw the next bone.

Before we do, let's see where we can see the existence of the bone.

The bone (Bone2 in this case) is now listed in the list of objects on the left side (in the Groups panel), just below the mesh object QMesh1.

The Object Properties panel on the right side  shows the name of the bone object as Bone2 in this case.

Click the name to rename it.
Enter a more descriptive name for this bone. Such as top bone.

Now the bone's new name is showing in the Groups, as expected.

While we're at it, we should also rename the leg from its cryptic name (QMesh2) to something more descriptive, like whole leg (mesh)

I've added (mesh) in the name just to remind me that this is a mesh object.

It's time now for the next bone. Start drawing the second bone just below the knee.

Draw the line towards the ankle.

Release the mouse or tablet button and optionally again draw the sizes of the spheres at either end.

And so on and so forth, now you know the drill. Draw all desired bones into the leg in this way.

In the Object menu, find the Hide menu item, or hit "H" to temporarily hide the mesh object if you want to only see the bones.


Step 3: Skinning the object...
