S1N Group for Houdini

S1N_Group improves asset preparation based on a workflow through hierarchical organization. This SOP-based HDA provides an intuitive way to structure and organize assets more efficiently by offering tools to simplify common tasks. Inspired by hierarchical workflows and the Solaris Scene Graph Path.

Changelog – Version 1.102

• Significantly improved tolerance to large datasets.
• Added a new filter for subsets.
• Rewrote the logic of the Rename module — now much more stable and faster.
• Improved performance by 2x with heavy geometry inputs.
  

Changelog – Version 1.1.01

• Optimized subset processing for faster execution
• Created a new initial hierarchy loading system to enhance the experience when working with assets that have heavy data loads.
  

Changelog – Version 1.1 (Major Update)

• A newly implemented tool, Manage Subsets, allows for quick and intuitive management of GeomSubsets.
• The Batch Rename tool has been redesigned and improved — you can now preview changes in real time before applying them.
• Fixed an issue where the HDA scale wouldn’t adjust properly when using Houdini’s Global UI Scale setting.
• Implemented a global rule so that pressing the spacebar no longer inserts blank spaces; instead, it produces an underscore (“_”), mirroring Houdini’s native behavior.
• The menu interface has been redesigned to include a new category called Tools, which contains the most specialized tools for highly specific tasks.
• Isolate Color Subsets has been added to the Sync section. It enables or disables the preview of subsets when the Isolate Color option is active.
• A visual badge was added above value icons in the hierarchy to highlight which items include GeomSubsets.
• The documentation has been updated to version 1.1.
• A new USD / Export to Solaris button was added to the HDA. It creates a SOP Import node configured to transfer all required attributes to the USD Stage.
• Stability improvements and minor bug fixes.

Key Features

🔹 Visual and Hierarchical Organization
• Manages string attributes within a hierarchical tree, structuring and organizing values with clarity.
• Enables the creation of groups or parent nodes to logically cluster elements, preserving the original placement of values within the hierarchy.
• Offers the ability to merge similar items into a single visual entry without altering the underlying data.

🔹 Interactive Drag & Drop Interface
• Allows intuitive reorganization of attribute hierarchies through drag-and-drop functionality.
• Facilitates grouping, merging, and renaming of string attribute values directly within the editor—no coding required.

🔹 Attribute Management
• Features dynamic filtering for rapid searching of string attributes.
• Provides batch renaming capabilities with options such as:
• Supports adding, modifying, and deleting any attribute value, offering complete flexibility in attribute management.

🔹 Real-Time Geometry Synchronization
• Automatically reflects changes in geometry without the need to manually run scripts.
• Includes an "Isolate Geometry" function that allows you to focus on specific elements in the viewport with a single click.

🔹 Robust Undo/Redo System
• Integrates a comprehensive Undo/Redo mechanism that captures the state of the hierarchy, allowing users to revert or reapply changes seamlessly throughout the asset preparation process.

🔹 Customizable Color Assignment
• Assigns colors to string attribute values and displays these changes directly on the geometry.
• Automatically synchronizes color assignments throughout the hierarchy and supports importing colors from geometry.

🔹 JSON Data Export & Import
• Facilitates the export and import of attribute and color data in JSON format, enabling configuration reuse across projects.

🔹 Viewport Color Isolation
• Provides the option to isolate colors in the 3D viewport for enhanced visualization and focus on particular areas.

🔹 Group Creation and Merging
• Creates groups or parent nodes to systematically organize string attribute values within the hierarchy.
• Merges selected items into a single group with a custom name, inserting the new group in its original hierarchical location rather than at the root.

🔹 Support for String Attributes
• Efficiently manages string attributes such as name, path, and shop_materialpath.

Benefits

• Efficiency: Reduces asset preparation time with visual and automated tools.
• Flexibility: Seamlessly integrates with Houdini, Solaris, and USD workflows, offering robust management and deletion of any attribute values as needed.
• Reusability: Simplifies the export and import of configurations for use across various projects.
• Visual Workflow: Empowers artists to work intuitively without the need for advanced scripting knowledge.
