Sim Plugin C4D

Agent guidance for working with user-installed Maxon Cinema 4D through its native Python and command-line interfaces.

This initial release is skill-only. It helps an agent discover a local Cinema 4D installation, choose between c4dpy, command-line rendering, and embedded GUI scripting, and validate saved scenes and render artifacts. It does not bundle Cinema 4D, Maxon SDK files, render engines, or a background control service.

Contents

• skills/c4d/SKILL.md — native C4D workflow and safety guidance
• skills/c4d/scripts/probe-c4d.ps1 — portable, skill-owned read-only Windows installation/capability probe
• skills/c4d/references/ — Maxon-native API and probing notes

Requirements

• A licensed Cinema 4D installation supplied by the user
• The matching c4dpy and command-line renderer when those workflows are used
• PowerShell 7+ for the included Windows probe

Discovery probe

Agents resolve the probe from the installed skill resource directory rather than assuming a repository checkout or current working directory. The probe does not start Cinema 4D or test the license; it reports evidence that can be gathered without mutating application or account state.
