Houdini 21.0 Nodes Geometry nodes

APEX Scene Invoke 2.0 geometry node

Evaluates geometry from an APEX scene.

On this page
Since 21.0

This node evaluates the geometry outputs from an APEX scene. See animation workflow for examples of how to use this node.

Parameters

Output

Specifies how the evaluated scene outputs are combined into the output geometry.

Packed Geometry

Creates a folder structure of packed primitives, with one file per output. See the packed character format for more information.

Unpacked Geometry

Each scene output is merged into the output geometry. This is typically used to directly access the geometry from a single scene output. If there are multiple outputs, the Packed Geometry mode typically results in faster playback performance.

Path Attribute

When Output is set to Unpacked Geometry, turning this on creates a primitive attribute that contains the output path of the shape. This can be useful for identifying the different shapes if there are multiple outputs.

Animation

When turned on, the scene is evaluated using the Animation Clip at the specified Frame. When turned off, the scene’s animation is not used and the output geometry appears at its rest pose.

Animation Clip

The name of the animation clip to use. If left empty, the scene’s default animation clip is used.

Frame

The frame at which to evaluate the scene.

Character Shapes

When turned on, outputs the visible shapes for each character in the scene. This provides a simple way to output the geometry seen in the animate state, rather than using the Extra Outputs to select each shape individually.

Characters

A pattern specifying the characters to include in the output.

Note

This pattern is matched against the character’s name (i.e. electra, not /electra.char)

Shapes

A pattern specifying the shapes from the Characters to include in the output.

Include Invisible Characters

When turned on, characters hidden by selection sets are included in the output if they match the Characters pattern.

Extra Outputs

Specifies additional outputs to evaluate from the scene. This is used to evaluate outputs other than the characters' shapes.

Scene Output Path

The path to an output node in the scene (for example, /character.char/Base.rig/output). This typically fetches a dictionary of output data from a rig.

Key

The entry in the Scene Output Path dictionary to fetch (for example, Base.shp). This parameter is only used if the data at the Scene Output Path is a dictionary value.

Inputs

Scene

The scene geometry to load and execute.

Outputs

Scene Outputs

The result fetched from the scene evaluation.
