Prepare models for animation in Alias

00:00

As our animations become more complex, it's important to be disciplined in how you group and name the elements to be animated.

00:09

I'm using this mannequin model as it's a classic example of how to create group nodes

00:15

and groups of groups into a hierarchy that represents how the objects move.

00:20

And it's these nodes that the key frames and animation channels are applied to.

00:26

So, the Animation Editor shows the same hierarchy.

00:29

So, let's animate the left leg.

00:32

I'll do a keyframe here, then I'll rotate it and do a second keyframe.

00:40

It's only created keyframes for this left leg node.

00:45

And so now if I want to move the lower leg, I can animate this independently.

00:50

So, for example, I can set a keyframe for it here, and then here.

00:57

And again, it's only created free keyframes for this node, it hasn't added unnecessary ones for the other node.

01:04

So now I can play with the timing of these completely independently and without having created unnecessary keyframes.

01:13

So, it's very important to create group nodes for your model if you want to do animation.

01:19

So here for example, this car, the window moving down is a separate animation from the door opening.

01:26

And this side glass being grouped underneath the door assembly is what makes sure it always moves with the door as it opens.
