Begins the render with the last render control settings.

Opens the render control dialog to allow adjustments of the render parameters before rendering.

What frames to render.

The range of frames for the clip (start frame, end frame, and increment), inclusive.

All values may be decimal (for example, start on frame 1.5)..

Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.

Specifies the source of the agent definition that will be written to disk.

Path to the object subnetwork containing the character rig.

When enabled, the Character Rig path is used to specify which nodes to import by traversing its outputs instead of its children.

Pattern used to limit which nodes should be imported. Patterns using usual opglob syntax along with @‹bundle› references are accepted.

Optional mask to further restrict which object node types will be imported. Disable the toggles to prevent baking particular types.

Specifies a SOP network that contains an agent primitive.

Filename of the FBX file to generate agents from.

When enabled, create material_override attribute inside the shape geometry which imports the material values from the FBX that are suitable for use with Houdini’s Principled Shader material.

Specifies whether to convert to Houdini units when importing the FBX file.

Only import objects whose display flags are on. If you turn this off, all nodes in the character rig are imported into the animation clip.

When Minimal Nodes is enabled, specifies whether nodes containing deforming geometry are included in the agent’s rig and clips.

Combine polygon primitives into polygon soup primitives when creating the shape library. This can reduce memory usage, particularly when rendering with Mantra.

Create polygon soup primitives instead of polygon primitives when loading geometry from the FBX file. This can reduce memory usage, particularly when rendering with Mantra.

When importing a skinned mesh, additional capture regions with identity transforms are added to the boneCapture attribute for the ancestor joints of any captured joints. It is recommended to only enable this option for compatibility with older scene files, as it can introduce issues with unpacking or merging the rest geometry of multiple skinned shapes.

The default layer for the agent, created using the display flags of the objects. Every agent must have at least one layer.

Specifies a scale for the bounding box of each shape in the default layer. See the Agent Primitive help page for more information on how an agent’s bounding box is computed.

Generate a collision layer from geometry containing capture/deform weights. This generates capture region primitives and assigns them to the corresponding bones in the rig.

When Generate Collision Layer is on, the name of the collision layer.

Name of the baked out clip (agent animation). The animation is taken from the current scene.

Specifies the names of the animation clip(s). A clip is created for each take in the FBX file. The ${FBX_TAKE_NAME} and ${FBX_TAKE_INDEX} local variables can be used to generate clip names based on the take name and index from the FBX file.

Specifies whether to use the value of the Sample Rate parameter instead of the sample rate stored in the FBX file. This is useful if the application that exported the original FBX file did not set the sample rate correctly.

Sample rate to use for the clip when Override Sample Rate is enabled.

Adds channels from the specified CHOP node to the agent’s clip.

Shift output clips from the specified frame range to start at frame 1.

When enabled, this will create an extra joint named __locomotion__ which serves as a placeholder for factored out locomotion animation when Convert to In-Place Animation is enabled.

Convert a moving character animation to an in-place clip, by subtracting the positions of the Locomotion Node (relative to the origin or where it was on the first frame depending on Use Pivot from First Frame parameter).

The object inside the Character Rig that controls the locomotion of the character (the node in the character rig that has translation channels that move it forward in space). When Convert to In-Place Animation, Houdini uses this to remove the translation from the character animation to keep the character in place. (The crowd solver node assumes that the agent animation is in-place since it will be attached to a moving particle.)

The locomotion animation is placed in a separate transform in the rig named __locomotion__. If this parameter is empty, then __locomotion__ will use the Character Rig.

If this parameter and Locomotion Node are specified, the generated __locomotion__ transform will also contain rotational information using the vector from the Locomotion Node to the Locomotion Orient node. If this transform is the same as the Locomotion Node, its orientation will be directly extracted. This parameter has no effect if Locomotion Node is empty.

When creating the animation of the Locomotion Node, project the positions along the dominant axis of motion in the XZ plane. If the clip will be used as an in-place clip with the crowd solver, enabling this option can help to maintain hip swaying in the motion.

When creating the animation of the Locomotion Node, calculate the positions to be relative to the origin. If this option is disabled (the default), then the positions will be relative to where it was on the first frame.

Name of the agent. The parameter is provided for convenience so that it can be referenced via the $AGENT local variable in other parameter values.

Parent directory of agent definition files. This parameter is provided for convenience so that its value can be referenced via the $CACHEDIR local variable in the other filename parameters.

Filename for the agent rig. The rig file is a JSON file describing the transform hierarchy of the agent.

Filename pattern for agent layer files. The ${LAYER} local variable can be used to the include the name of the layer in the filename.

Filename for the agent shape library.

Filename pattern for agent clip files. The ${CLIP} local variable can be used to the include the name of the clip in the filename.

Filename pattern for agent transform group files. The ${TRANSFORM_GROUP} local variable can be used to include the name of the transform group in the filename.

Filename pattern for the agent definition’s metadata, which is a JSON file containing additional custom data.

When turned on, creates intermediate parent directories for output files as needed. Currently only applies to generated scripts, images, and shadow maps.

Execute this script before any baking.

Execute this script after all baking
