Plugin Manager "Create Reload Script" generates invalid Python string path on Windows

Anlv

Hi Community,

I noticed a small issue with Plugin Manager → Create Reload Script on Windows.

I often use Reload Python Plugins while developing Python plugins, but it reloads all Python plugins. In some cases, especially with renderer-related plugins, this can also trigger viewport/material refreshes.

Create Reload Script is very useful because it allows reloading a specific plugin only. However, on Windows, the generated script uses an unescaped path with backslashes:

plugins.ReloadPythonPlugin(
    path="C:\Users\<user>\AppData\Roaming\Maxon\Maxon Cinema 4D 2026_XXXXXXXX\plugins\PluginName\PluginName.pyp",
    reloadDocumentAfterReload=False,
    reloadOnlyActiveDocument=False
)

Running the generated script in the Script Manager causes:

SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

Manually replacing \ with /, using a raw string, or escaping the backslashes fixes the issue.

It would be great if Create Reload Script could generate a Python-safe path automatically on Windows.

Thanks!

Hey @Anlv,

Thank you for reaching out to us and reporting this. I just changed it so that the path is always a raw string. This will be shipped with an upcoming (but not the next) public release.

I.e., your script will then be as follows where there is an r in front of the string, which should fix the issue on Windows.

plugins.ReloadPythonPlugin(
    path = r"C:\Users\<user>\AppData\Roaming\Maxon\Maxon Cinema 4D 2026_XXXXXXXX\plugins\PluginName\PluginName.pyp",
    reloadDocumentAfterReload=False,
    reloadOnlyActiveDocument=False
)
