What is Houdini Folder-Based File Importer Tool

Houdini Folder-Based File Importer Tool is a Houdini Digital Asset for importing geometry files based on directory structure.


The tool converts folder hierarchies into organized geometry imports inside Houdini.


How the tool works

The tool scans a specified root directory and iterates through its subfolders.

Geometry files are imported automatically, preserving folder-based grouping and naming.


Pipeline usage

The tool is typically used at the beginning of a pipeline, after receiving external assets.

It allows large sets of geometry files to be imported deterministically without manual setup.

Performance Comparison

In a real-world project test, the Folder-Based File Importer showed an execution time of 2.396s, while the standard File Merge SOP took 2.625s.

In this scenario, I selected 3 .obj files with a total of 1,387,781 polygons. The comparison demonstrates the efficiency of the Folder-Based File Importer, which streamlines the process by automating file selection and filtering compared to the manual approach of the File Merge SOP.

Key Differences

  • File Merge SOP:

    • Requires manual selection of files.

    • Suitable for small datasets but becomes slow and inconvenient when dealing with large file sets or nested folders.

  • Folder-Based File Importer:

    • Automatically scans folders and subdirectories.

    • Supports file format filtering, ignoring unnecessary data.

    • Speeds up the import process and reduces manual tasks, saving significant time for the user.
