Keyframing objects on animation layers is very similar to regular keyframing. After you have added an object’s attributes to a layer, you can keyframe in your scene as usual.
As you key, visual feedback in the
Animation Layer Editor shows you the status of each layer. A green dot
displays next to the layer name if the layer is active, and a red dot
displays if the layer is affected. A layer’s status is determined by the keying mode you are using and whether it includes objects selected in the scene.
For additional information on the red and green indicators, see Active keying feedback. To better understand when a layer is active or affected, see Animation layer states.
You can always keyframe objects in your scene without adding their attributes to layers. If necessary, you can extract that animation onto layers later. See Extract animation from your scene onto a layer.
To keyframe on animation layers
- Create layers for as many objects or attributes as you require to organize your work. See Create animation layers.
-
Add and remove attributes from your animation layers to organize which attributes will be keyed on each layer.
For example, if you create two layers for animating a sphere, you can add its Translation attributes to one layer and its Rotation attributes to the other.
- In the
Animation Layer Editor, select the keying mode you want to use from the
Animation Layer Editor menu bar Options menu.
Three keying modes let you set how layers become active for keyframing:
-
Key in Selected Layer(s)
This is the simplest keying mode. When Key in Selected Layer(s) is turned on, a layer must be selected to be active for keying.
Note:When using this keying mode, you must select the BaseAnimation bar to set keys on objects that are not included on animation layers.
- Key in Last Active Layer(s)
When Key In Last Active Layer(s) is turned on, Maya Creative automatically selects which layer is active. In this mode, the active layer is the last layer you added for the selected object. For example, if you have added AnimLayer1, AnimLayer2, and AnimLayer3 for an object, AnimLayer3 is active if you select this keying mode.
- Hybrid
This is the default keying mode for layers and it provides a combination of the previous two keying modes. When Hybrid keying mode is on, Maya Creative sets keyframes on the last added layer for the selected object, unless you have selected a different layer.
Refer to the Animation Layer Editor menu bar Options menu for more detailed information on each keying mode.
-
Key in Selected Layer(s)
- Manipulate and keyframe objects in your scene as usual. See
Set keys.
As you set keys, use the Active keying feedback to monitor which animation layers are being keyed.
To set the key tick color for each animation layer
Setting the layer ghost color also sets the layer’s key tick color in the Time Slider. See 'To set the ghost color' in Display ghosts for layered animation.
To change the size of key ticks, see Customize the Time Slider.
Setting Zero keys
Zero keys let you define a point in time where you want the layer’s animation to have no offset from the original animation. Using Zero keys, you can demarcate the time range where you want a layer’s animation to start and end.
For example, if you have an animation sequence of 50 frames and you only want to modify the animation between frames 20 and 30, set Zero keys at frame 20 and 30 to bracket the area you want to edit. Create your modified animation between frames 20 and 30, then play your result animation. The original animation plays fully before frame 20 and after frame 30, with your modified animation playing fully in between.
To set a Zero key
- Click
in the
Animation Layer Editor.
Note:As you set a Zero key, the object(s) you are keyframing may move if it is not at its ‘zero’ position from the original animation.
