Missing Arnold Shaders with htoa-6.1.3.1 py37 Houdini 19.5.303 on Ubuntu 20.04

These are my env file, Houdini variables and the version of Arnold I installed.

For all I can tell everything in Arnold is working except for the shaders which are all missing from both /mat and /shop.

Even the Arnold VOP network is not there, and I have no "Arnold" at the top of the Tab-menu in any of these contexts.

 

I tried removing all my other plug-ins but nothing seems to fix the issue.

I also checked the license and everything is up.

There is no traceback error when opening or closing Houdini.

 

However when I try to create an Arnold light I am met with this error:

Same thing happens with the Arnold Volume node in /obj:

Other than that the Arnold menu is showing at the top and I can create Arnold ROPs in /out.

 

How can I go about fixing this?

 

Thank you for reading and have a nice day.

 

EDIT: One more thing; I also switched the ACES and Arnold orders in the .env file but to no avail Im afraid.

The default Houdini 19.5 install is the Python 3.9 version of Houdini

You have the HtoA for Python 3.7

 

What Houdini did you install? 3.7 or the default (3.9) ?

Oh that seems to have fixed it. Didn't think of that!

Thank you so much Stephen
