Animation Timeline and key frames¶
The Timeline is the place to begin the creation of your keyframe animation. On any selected prim you can animate the transforms, property values and token attributes.
Allows the user to set the Framerate for the current stage and the animation you create. Determines how many frames per second will be played.
Allows the user to control the current position in time.

The Key all button will create a key on all transforms and the visibility channel of the selected Prim.
Multiple prims can be keyed simultaneously.
This action can also be performed with the Hotkey (ALT-S).
Activate autokey to automatically generate keys when you change parameters that have curves. Note: Autokey will only work if an initial key has been created by the user for the specific channel being animated. Autokey requires a curve to exist in order to create a key.
A Grey Autokey Icon indicates that autokey is turned off.
A yellow Icon indicates that there is no curve present on the selected prim - Create a key on the prim to enable autokey.
A Red Autokey Icon indicates that Autokey is active on the currently selected prim.
Autokey ALL transforms¶
By default Autokey will only update channels that have changed. EG. if trans X Y and Z have keys on frame one and you move the object on the Y axis only on a subsequent key, only the Y channel will be keyed.
Autokey all transforms, Selecting this option will set autokey to key ALL transforms and Visibility if any channel is updated on a given frame. Effectively autokey executes the ALT S command when a change occurs to the objects transform values.
Provides a quick link to the movie render options.
Creating and Editing Keys¶
You can create keys in a number of Ways. Using the key all (ALT S) and Autokey options mentioned above or for more more explicit control of individual channels, you can right click on a channel in the channel box.
To get Started, with a Prim selected you can create keys in a number of Ways. Using the key all (alt S) and Autokey options mentioned above or for more explicit control of individual channels. You can also go to the property panel and right click on the transform or property value channel to “set key”. Once the first key is created you can then use autokey. (note: a curve must be created on a channel before autokey will create keys for that curve. Do this by creating the first key with either option described above.)
Setting keys in property panel¶
Right Click over Translate Rotate or Scale to key all three axis of the selected transform type. Right Click over an individual axis channel - to key ONLY that channel.
