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
