Why Windows server not supported? Feb. 5, 2024, 12:18 p.m.


Windows Server has never been supported. It's even mentioned in the Houdini 19.0 systems requirements: []

We don't support Windows Server because we don't actively test on that OS. Some users still run Houdini on Windows Server but they do so at their own risk. If they encounter a bug that's specific to Windows Server (i.e. it can't be reproduced on Windows Pro), then there's no guarantee that they will receive a fix for it.


'HFS' environment variable not set? Oct. 10, 2023, 11:33 a.m.

Where do you set them? in Environment Variables?

My py23convert.bat is not working and it gives me this error: "The system cannot find the path specified."
I think because of %HFS% inside it.

You can set environment variables within the the command prompt terminal using the Windows `set` command.

However, if you want the basic Houdini environment variables set in your terminal, then it's better to just launch the Houdini Command-Line Tools terminal instead, either by typing "Houdini Command-Line Tools" in the Windows Start menu or by double-clicking on C:/Program Files/Side Effects Software/Houdini X.Y.ZZZ/bin/hcmd.exein the Windows File Explorer.

The Houdini Command-Line Tools terminal is the same as the Windows command prompt terminal but with the Houdini environment source'd so variables like %HFS% are already set for you.


Linux: resizing Houdini window(s) hard/impossible May 23, 2023, 10:46 a.m.


There's not much to update on the development side. I've been re-architecting things in Houdini to avoid the bug but there is no chance that I can backport the changes to Houdini 19.5.

However, Jason and company recently brought to my attention a workaround in KDE:
If we enable the SystemSettings->DesktopEffects resize window as fast-texture-scale, then it resizes without issues
Note that KDE removed the resize texture scale effect setting in 5.24 but from my understanding the Houdini window resize issues don't appear in newer KDE versions anyway.
