Hi @originalthinkingstudio,

The Python script you are trying to run seems to rely on 'MaxPlus', a Python module that was deprecated with the introduction of Python 3. The last release Python 2.7 was still present in the product was for 3ds Max 2021. Starting with 3ds Max 2022, Python 3 was the only Python interpreter and 'MaxPlus' was then not present anymore.

On which version of 3ds Max are you trying to use your script?

Thanks for the reply
I'm working on the 2023 version

Is there a solution to run it on version 2023
Or do I have to install the 2021 version?

[eric.brosseau · Accepted solution]

There are two options. you either:

• run your script on a 3ds Max 2021 with the command-line option '-pythonver 2' (or set the environment ADSK_3DSMAX_PYTHON_VERSION=2) - detailed here; or
• the vast majority of MaxPlus functionalities can be converted to use the 'pymxs' Python module, our MAXScript exposure to Python.

I have taken a look (really rapidly) at the 'main.py' file in the archive you provided in the original post. It seems MaxPlus is used for only two trivial cases:

1. executing a MAXScript script from within Python

    MaxPlus.Core.EvalMAXScript(
       'filein @"{}"'.format(os.path.join(ROOT_DIRECTORY, cls.ValidatorFileName)))

   This can be converted to the pymxs.runtime 

   rt.filein(os.path.join(ROOT_DIRECTORY, cls.ValidatorFileName))

2. The other call wants to get the main Qt widget of the 3ds Max by making this call

   MaxPlus.GetQMaxMainWindow()

   We introduced a new Python helper module directly dealing with PySide2 (Qt) objects called qtmax. The call would be simply this (once you import qtmax into your script)

   qtmax.GetQMaxMainWindow()

I hope this help. As a free gift, I have included a working main.py file (this only file in the zip archive attached to this message) with the changes required and described here.
