Houdini 21.0 Nodes Geometry nodes

APEX Scene Add Animation 2.0 geometry node

Adds animation to an animation scene.

On this page
Since 21.0

This node adds a new animation clip that contains animation in the form of channel primitives to the animation scene. The animation clip is added as a .clip folder in the scene’s character folder structure under the /animation folder. See animation workflow and the motion mixer for example uses of this node.

Parameters

Character

Character

The name of the character to apply the animation to, for example, electra.

Rig

The character’s rig to apply the animation to. This is specified using the name of the rig. For example, if the rig’s full path is /electra.char/Base.rig, set Rig to Base.

Animation Clip

Clip Name

The name to give the animation clip containing the new channel primitives. A .clip extension is added to the name if it’s not already included.

Controls

An APEX path pattern that specifies the Rig's controls whose channels to update. This limits the channels that are added to the animation clip from the input geometry.

Replace Existing Animation

When turned on, the new channels replace the existing animation clip. When turned off, the existing channels are kept unless they are overridden by a new channel.

Input Type

Input Type

The format of the second input’s geometry.

Channel Primitives

The geometry contains the channel primitives to add to the animation clip.

Animation Parms

The geometry contains a parms detail dictionary attribute with animated values (for example, from the APEX Control Update Parms SOP). Channel primitives are created from these animated parameter values over the Clip Range.

Clip Range

When Input Type is set to Animation Parms, this specifies whether to read the motion clip’s frame range from the clipinfo detail attribute on the input geometry, or use a custom frame range.

Frame Range

When Input Type is set to Animation Parms, and Clip Range is set to Custom Frame Range, this is the range of the input frames to grab.

Create Keys with Auto-Tangents

When turned on, sets the auto-slope flag on all the created keys, and adjusts the slope and acceleration values. Keys with their slopes set to automatic are drawn as diamonds in the animation editor graph view. When turned off, the slopes are flat (with a value of zero) and the auto-slope flag is off.

This parameter is available when Input Type is set to Animation Parms.

Inputs

Scene

The animation scene to add the animation to.

Channel Primitives

The animation to add to the scene.

Outputs

Scene

The animation scene with the added animation clip.
