Now we need some empty groups,
00:06
press control ng to create a group,
00:09
rename it to inner left bank group.
00:13
Duplicate this and change the name to outer left bank group.
00:17
These will be used to pivot the foot as it banks from side to side,
00:22
match both of these to the heel joint.
00:25
So we get the same orientation as the reverse foot.
00:28
Now move these. So the inner bank group is on the inside of the foot
00:34
and the outer bank group is on the outside.
00:37
Next parent them to the foot I care control.
00:41
So here we have the two groups
00:43
now parent the outer bank group to the inner bank group.
00:48
Again, we need to control the rotations directly.
00:51
So we need to clean the values.
00:54
There we go.
00:55
So the foot will pivot something like this.
00:58
Now parent the reverse heel joint to the outer bank group.
01:03
So you see the groups will move the foot
01:06
like this
01:07
and this
01:09
let's hide the reverse foot for now
01:12
and switch to wireframe. So we can see the joints.
01:15
We are now going to use a series of
01:17
handles to control the foot and toes.
01:20
So open the ICA
01:21
handle tool options.
01:23
First,
01:24
if you remember we connected the foot I care
01:26
joint to the control using an orient constraint.
01:30
So we could animate and pose the foot.
01:33
We're going to change the way this works now.
01:35
So let's find and delete that constraint node.
01:38
Here it is
01:40
create a single chain solver from the foot IK joint down to the new ball I care joint.
01:47
You see we can use this now to control the foot's orientation
01:52
and it will work better with the I
01:54
limb.
01:55
Now create four more I
01:57
handles spanning each section of the tours.
02:00
So we have five in total.
02:03
Let's quickly rename these to match the joints they are driving.
02:08
Ok.
02:09
Now parent them to the foot, eye care control so that we can move the foot as before.
02:15
But if we move the control down,
02:17
you see the foot and toes follow
02:20
as if the foot has peeled from the floor.
02:23
So it's a much more natural movement.
02:26
Let's bring back the reverse foot.
02:29
We have the main driver I care handle here,
02:32
which was a key part of the quadruped limb.
02:36
It's currently parented to the foot control,
02:38
but we need it to instead follow the reverse foot.
02:41
So as the ankle lifts, the rest of the leg will follow
02:45
and the knees will bend
02:47
quickly, parent it to the reverse foot, ankle joint.
02:51
Now parent the first two I care handles to the reverse foot ball joint
02:57
and finally move the other eye care handles.
02:60
So they are parented to the reverse toe joint.
03:04
So they are all moving with the reverse foot now
03:07
and we compose it.
03:09
So it's on its toes.
03:12
Actually, let's move these. So they are pounded to the toe joint too.
03:18
Ok. That looks better.
03:21
Now, move the ball I
03:22
handle. So it's pounded to the reverse ball joint.
03:26
Ok. Those are all set up now.
