Another small tip: you can simply use a single <br> for line breaks — there’s no need to use <b> or </b>.

Also, just like in the script example, scripts can support localized language strings as well:

"""
Name-US:Example
Name-CN:示例
Description-US:Example line 1.<br>Example line 2.<br>Example line 3.
Description-CN:示例第 1 行。<br>示例第 2 行。<br>示例第 3 行。

Hi everyone, I’m releasing Plugin Debug Manager, a debugging utility for Cinema 4D Python plugin development.

When working on a .pyp plugin, changing a single entry file can otherwise require reloading every Python plugin—or restarting Cinema 4D. Plugin Debug Manager reads the currently registered Python plugins and lets developers reload only the entries they are testing.

Main features:

Reads registered .pyp and .pypv plugins from Cinema 4D
Groups multiple registrations by their actual entry-file path
Displays plugin names, icons, decimal IDs, registration types, and full paths
Filters entries by filename or plugin ID
Reloads one plugin, selected plugins, or all reloadable plugins
Supports click-and-drag checkbox painting for batch selection
Persists checked entries and can move them to the top on demand
Provides Reload Plugin, Reload All, Fold All, and Unfold All context commands
Locates plugin files in Explorer or Finder through c4d.storage.ShowInFinder()
Continues processing when an individual plugin fails to reload

Implementation details:

Registry entries are collected with c4d.plugins.FilterPluginList(c4d.PLUGINTYPE_ANY, True)
Entry files and registration metadata are obtained through BasePlugin.GetFilename(), GetID(), and GetType()
Selective reloads are performed with c4d.plugins.ReloadPythonPlugin()
ReloadDocumentAfterReload(True) is called only once after the reload batch

Before reloading, the manager copies and normalizes the target file paths instead of retaining BasePlugin objects that may become invalid during the reload process. The manager itself remains visible in the list but cannot be selected or reloaded.

Compatibility:

Current target: Cinema 4D 2026.3.3
Selective reloading depends on c4d.plugins.ReloadPythonPlugin, available in this version
Other Cinema 4D versions have not yet been verified

Version: 1.3.0
Plugin ID: 1069486
Author: Anlv
Download: Plugin Debug Manager v1.3.0.zip

By the way, this is open source, and you can edit and modify it yourself to make it better suit your work habits.

Best regards,

Hi, @atg Simply remove the invalid child IDs after the commands recorded in the script log, for example:

c4d.CallCommand(1062577, 1067510) → c4d.CallCommand(1062577)

I remember encountering the same issue before, but I can’t quite recall the details. I need to look it up.

import c4d

doc: c4d.documents.BaseDocument  # The currently active document.
op: c4d.BaseObject | None  # The primary selected object in `doc`. Can be `None`.

def main() -> None:
    """Called by Cinema 4D when the script is being executed.
    """
    c4d.CallCommand(1062577)  # Mesh Emitter

if __name__ == '__main__':
    main()

How do I retrieve a command call from it's index number ?

Cheers,

@ceen Hi, The Summary row mey only a UI aggregate; it is not a single CTrack that can be switched directly.
To reproduce its Animation switch, collect the real CTrack objects and set their c4d.ID_CTRACK_ANIMOFF value:

# True = animation enabled, False = animation disabled
track[c4d.ID_CTRACK_ANIMOFF] = False

This does not delete keyframes and does not hide Timeline rows. Do not use NBIT_TLx_HIDE for this, because those flags only hide rows in the Timeline.
A complete document-wide solution must also traverse Motion Sources in doc.GetNLARoot() . Add Motion Source moves/copies animation into that separate NLA hierarchy, so iterating only normal scene objects and tags will miss tracks such as Time and 2D Tracks.

It should be noted that doc.GetNLARoot() is marked as Private in the SDK, and I'm not sure whether it should be used.

"""Toggle the Summary Animation switch for all collected CTracks."""
