Solved Content of PYTHONPATH not appended to sys.path

Hi, this is my first post in the new forum. I'm exited :wink:

I noticed, that the content of the PYTHONPATH environment variable is not appended to the content of sys.path for the c4d python interpreter. Since we use a lot of site-modules in our company, this issue is rather annoying.

For the time being I helped myself by updating sys.path during plugin initialization, but I rather would not.

# extend sys.path whit content of PYTHONPATH
python_path = os.environ['PYTHONPATH'].replace("\\", "/").split(';')
for entry in python_path:
    if not entry in sys.path:
        sys.path.append(entry)

Is there a way to tackle the problem in a more convenient way, like a command line parameter or an environment variable? Is this behavior intended or is it just overlooked during the R20 upgrade process?

I looking forward to your answers,
Cheers,
Heinrich.

Hi, correct this is a known issue, I should have mentioned in the Changelog, I will update it next week.

We removed the usage of PYTHONPATH since it's too problematic in case of multiple Cinema 4D versions installed and since PYTHONPATH can be used for a large variety of scripts that could not work in Python 3.7

Hi Heinrich,

Welcome to the new forum :grinning:

PYTHONPATH not added to sys.path is a known issue and has been already fixed for the R20 SP2 update.
I don't see a better workaround then your with R20 SP1 currently.

I turned this topic into a Q&A. Please use this functionality in the future. For more information see Q&A New Functionality.

Hi,

the issue is reappearing in R23.008, I'm wondering if this is a known one.

thanks in advance,
ben
