- [Instructor] Before we get started,

let's have a look to the rig.

By default, the character is presented with a MatCap

and the preview of the texture.

You can enter material preview mode

to see the robot at its best

but you should stay in showing mode

for animation performances.

(whoosh)

By default, you should have access

to the different rig layers.

If it's not the case, open the text editor.

You should have the script open,

if it's not the case, select it in the list

and press the play button.

Then select the rig

and go into pose mode.

The first thing to check is this eye icon.

It's a bone that holds some custom properties.

The Bevel option allows us to re-enable

the Bevel modifier that is on the robot.

It will make it look a little better

but it will also increase the number of polygon,

hence reducing the performances.

Activating the Bevel modifier

tend to triple the number of polygons.

Enabling the subdiv option,

will enabled the subdivision modifier on the robot,

increasing the number of faces to almost a million.

So it will largely slow down your computer performances.

If I press the space bar and try to play the animation,

even if our robot is not animated,

you can see the number of frame per second dropping.

Note that those option only effect the viewport display.

You don't need to re-enable them

if you want to render your animation.

Getting back onto this view property bone,

you can see that there are options to

mask the artillery piece, the legs,

and both the mini gun, and the rocket launcher.

Just, as we add on the squirrel character allows us to focus

on specific parts of the character.

Next to these bones,

we have another one that is our properties bone.

It includes a lot of different properties

but they almost all do the same thing.

The first ones allow us to switch

between the forward kinematic and inverse kinematics

for the right leg or the left leg.

By default, they are set to inverse kinematics.

Moving the inverse kinematic controller

would allow us to animate the whole leg

exactly as we did with our squirrel characters.

If we change the value to zero,

now the leg is moving in another position.

It will now follow the forward kinematic controllers

that we can access

by activating the forward kinematic layer.

Now the leg is moving using forward kinematic

and we can control each segment separately.

We will be mostly animating using inverse kinematic

so you can switch it back.

The next properties allows up to enable or disable

the rotation follow of the different parts of the robot.

By default,

the arms are following the orientation of the body.

But if I disable this flow rotation,

you can see that now they stay

or (indistinct).

They don't follow the rotation

of the body anymore.

You will find the same option

for the artillery piece and the head of the robot.

By default, the follow rotation is disabled

but if I re-enable the follow head rotation,

you can see that now the head is leaning forward

and is aligned with the body.

The follow leg rotation will only affect the leg behavior

whenever you are using forward kinematic.

This is pretty common when using forward kinematic

for the arms or the leg to isolate their rotation

from the hips rotation, or the shoulder rotation.

The next option, mini gun speed,

will allow us to set

the speed of rotation of the mini gun cannon so that

we don't need to animate the rotation of the barrels.

The mini gun follow and the sensor follow,

allow us to isolate the targets

from both those items.

The mini gun and the sensor will follow their own target.

And by default, those targets are parented

to the body of the robot.

If we disable or set to zero

the value of the follow option,

the target are no longer following the motion of the body.

And so you can see the mini gun adjusting its orientation

toward the aiming point.

And so does the sensor on top of the robot.

(whoosh)

The controllers of the robot are pretty straightforward.

The root bone allows us to move the whole robot

the torso root allows us to move the whole body.

Then you will find controllers for the different parts.

All targets for the legs,

IK controllers,

allowing to move and rotate the feet.

On the back of the foot, you will find

a very useful controller that allow us to perform steps

or rotation around the ball and the heel of the foot.

When you rotate it from the front view or on its Z axis,

you will get a nice contacting left to right motion.

Both arms of controller,

the rocket launcher as a door opening controller,

each body part as a separate controller as

on the body of this squirrel character.

Each rocket as its own controller

that allows us to move them in space at will.

And they also have a secondary controller that alow us

by a simple one axis rotation to deploy the wings

of those rockets.

The antennas have a simple one axis rotation control.

The artillery as a first controller

that allows us to create the recoil motion.

And we also have a nigary controller that allow us

a bit of up and down motion

and also to slightly rotate the artillery back and forth.

So it's a pretty simple yet versatile rig.

Let's animate this beast.
