How To Create An Animation Path In Houdini

Hello at that place

How to set keyframes

At the object level, select and transform objects and characters to position them for keyframing.

Selecting an object automatically scopes (makes cardinal-able) commonly animated parameters in the channel list and/or blitheness editor. To scope other parameters, or change which parameters are automatically scoped, run into how to scope parameters.

To...	Practice this
Set keyframes on all scoped parameters	Press Thousand or cull Edit ▸ Ready Keyframe.
Set keyframes on all parameters of the current operator'south active handle	⌃ Ctrl + M Printing on the handle and choose Channels and Keyframes ▸ Ready Keyframe.
Fix keyframes on the selected object's position	⇧ Shift + T
Set keyframes on the selected object's rotation	⇧ Shift + R
Set keyframes on the selected object's scale	⇧ Shift + E
Cardinal everything	Press ⌃ Ctrl + A to select all, and then printing K .
Protect certain parameters from beingness keyframed	In the parameter editor pane, press on the parameter and cull Lock Parameter.
Automatically create keyframes whenever y'all change parameters (auto-cardinal)	Turn on the Auto key button on the playbar. Run across car-key for more information.

Meet also how to edit keyframes and channels.

Tip

Yous can set the default curve function for new keyframes in the animation preferences (Edit ▸ Preferences ▸ Animation).

How to set and manage keyframes in the parameter editor

To...	Do this
Set up a keyframe on a parameter	Press on a parameter and choose Channels and Keyframes ▸ Prepare Keyframe. As a shortcut, you can click the parameter with Alt + to set a keyframe.
Remove a keyframe	Move the playbar to the keyframe for the parameter. Printing on a parameter and choose Channels and Keyframes ▸ Remove Keyframe. As a shortcut, you tin click the parameter with ⌃ Ctrl + to remove a keyframe.
Move the playbar to the next/previous keyframe for a parameter	Press on a parameter and choose Channels and Keyframes ▸ Pace to Previous Key or Channels and Keyframes ▸ Step to Next Fundamental.

Tip

For parameters with multiple components (for example, a position parameter with X, Y, and Z values) you tin click individual component text boxes, or click the parameter label to affect all components at once.

Color coding for keyframes and parameters

Houdini color-codes the groundwork of parameter edit fields in the parameter editor, and the keyframe ticks on the playbar timeline, according to the current keyframe status.

"Awaiting changes" means yous've changed i or more than parameters so the value is different from the previous keyframe, merely you haven't fix a keyframe to salvage those changes yet.

The timeline only shows primal markers for the currently scoped parameters.

Background	Timeline marking	State
Green	Green	Keyed This component is animated and y'all're on a keyframe.
	Vivid green	Fractional key 1 or more of the scoped channels are keyed at this frame, but non all.
Yellow	Orange	Pending changes You lot've changed this component on a keyframe, just not committed the change. You can fix Houdini to automatically commit changes on keyframes.
Light blueish		'Tween This component is animated (either with keyframes or an expression), merely you're not on a keyframe. (Click the proper noun of a parameter to switch between showing the electric current value and the expression.)
Steel bluish		Disabled cardinal This component is animated (either with keyframes or an expression), but the channel is disabled in the dopesheet.
