Houdini 19.5.569 Windows 11 Python 3.9

[terenceHYG92]

Hello all. I'm aware Arnold has the Python 3.7 version, but does it support the Houdini Py3.9 version?

Thanks!

[Stephen.Blair · Accepted solution]

The default download is Python 3.9
No "py" extension? That means the download is an HtoA that matches the default Python version of Houdini

[terenceHYG92]

To me, it would seem reasonable that on that downloads page, there would be an * that states Py3.9 is now the default, and the install isn't labeled as such. IMO.

It's working properly now, thanks.

Thanks!

Can you tell us more about the problem? Does HtoA not load, and you don't see anything in Houdini about Arnold?
Or does it load and give you errors when you try to use it? If so, what errors?

Hi thanks for you answer... I install arnold on the default route... and I cant see anything in houdini about arnold..

Most likely, houdini.env is the problem.

The HtoA installer updates the houdini.env in your User folder. For example:

• C:\Users\blairs\Documents\houdini19.5\houdini.env

But Houdini uses the houdini.env from the One Drive folder. For example:

• C:\Users\blairs\OneDrive\Documents\houdini19.5

So, you can copy the HtoA settings from the houdini.env file from the User folder to the One Drive folder.

One Drive is included with Windows 11.

Let's see the details from Help > About Houdini > Show Details ?

Ah. That's the problem with posting in a Solved thread that has "Windows 11" in the title 😉

HtoA 6.2.4.1 requires Houdini 19.5.752, you'll have to upgrade Houdini...or use an older version of HtoA

[cm403270]

Thank for you help, I try with a arnold old version ... Any news  I tell you dude... thanks 

[cm403270]

No dude.. I tryed with the old version to arnold and the new houdini version and I  can't install arnold

[Stephen.Blair]

Almost all problems are because of either Houdini/HtoA versions mismatch, or incorrect environment set up.

The only way to check is to check the houdini.env (or pkg file, if that's what you use), and the info from Help > About Houdini > Show Details.
