Houdini Hipfile Diff Tool


Recommended Posts

I've developed a Houdini Hipfile Diff Tool to address the challenge of tracking changes in Houdini hipfiles. This tool, inspired by 'git diff', offers a dual-view comparison, visual indicators for changes, synchronized navigation, and a search feature. It's tailored for the Houdini environment using hython 3.9.

The tool is open-source and available on my GitHub:https://github.com/golubevcg/hip_file_diff_tool

I also have a small article on my website about this tool: https://golubevcg.com/post/comparing_hipfiles_in_houdini:_the_diff_tool

Feedback and collaboration are welcome. If you encounter any bugs or issues, please don't hesitate to send me a message. Let's refine our Houdini tools together.

Super useful. Is this a wrapper around the diff tool that ships with houdini via command line?

Not exactly - it just uses the hou module to iterate over each node and each param of the node, and in the end, it just compares two dict between source and target scenes.

Hey Jesper!
My apologies for such a late answer!
So, most of the testing I did was on small-to medium-sized scenes, and it worked quite well. Some friends of mine tested on several larger scenes - no complaints yet. If will you have any problems, please feel free to reach out!

I've just released Version 1.1 of Hip Diff Tool.

Key Highlights of v1.1:
- Enhanced Visibility: Node input connections are now visible in diffs.
- UserDataDict Support: Added support for diffs in per node userDataDicts.
- String Diff Window: New window for comparing longer strings, scripts, or dictionaries.
- Efficient Collaboration: new option to share links to specific nodes or string diff windows, integrated into studio workflows with environment variable setup.
- Simplified Defaults: 'Show only edited' is now checked by default.
- API Enhancements: Significant improvements and refactorings for a smoother experience.
- Improved API unit testing coverage.
