Explore creating and configuring Python panels in Houdini, including setting up a custom Python panel path, environment variables, and packaging character tools as a reusable plugin.

Explore building a Houdini Python panel that imports character tools, defines a Qt widget class, and constructs a dynamic, group-based interface with pose and keying buttons for rig packaging.

Develop a Python panel in Houdini by adding and wiring a zero pose button, refining the interface layout, and implementing selection handling for a rig main node.

Learn how to connect and organize python panel buttons for Houdini KineFX rig packaging, duplicating and configuring zero post, key post, default post, mirror pose, and t-pose.

Build and organize a Houdini Python panel with tabbed layouts, add and test buttons for set default pose and channel groups, and debug interface stability.

Set up a basic pose library in Houdini KineFX rig packaging by configuring the pose library folder and path, and enabling scan and load workflows with JSON storage.

Implement a scan function to retrieve the library path, validate or create the directory using OS utilities, and prompt the user to create the pose library when needed.

Save poses to an entry in the pose library by selecting the library path, collecting key parameter values, filtering non-keyable items, and writing a readable json file with overwrite checks.

Load poses dynamically from the library, populate the load list, and apply saved poses to the character using Python to read directories, parse JSON, and update the interface.

Update the Python panel to build a two-part pose library with a main interface and settings, including save and load functionality, a file browser, and basic Qt widgets in Houdini.

Create a scrollable pose library with a grid of placeholder buttons, arranged in three columns, and wire each button to the load pose function.

Configure the Houdini KineFX pose library via the Python panel to select a directory with the file chooser, resolve an absolute path, and scan or create the library when needed.

Implement the pose save feature in houdini kinefx, updating the save button, validating name and path, and saving pose data as json with png thumbnails.

Save poses and generate thumbnail icons for each pose using Houdini flipbook rendering of the current frame, via a Python script and flipbook settings, to populate a pose library interface.

In Houdini KineFX rig packaging, learn to implement button icons by dynamically creating pose library buttons, setting a default pose library path, loading poses, and rendering icons with background images.

Clean up and optimize the Houdini KineFX rig packaging workflow by removing debug prints, refining the pose library layout, adjusting flipbook settings, and preparing the character picker.

An update fixes key character picker bugs in Houdini 20.50.297, enabling opening from the window menu, selecting rigs, and configuring the target node and controls; a minor audio-related crash remains.

Explore the Houdini KineFX character picker, selecting the HDR rig via the interface, and manage two rigs, bugs, and workarounds with JSON export/import and viewer state tweaks.

Explore the default character picker in Houdini KineFX Rig Packaging: set up, label, and color-control buttons, save as JSON or SVG asset, and explore tabs and Python panel options.
