C4D2Blender

Carpediego in Import & Export

C4D2Blender

This add-on is designed to streamline the workflow between Cinema 4D and Blender. Its main function is to automatically detect the most recently exported scene from Cinema and bring it into Blender with all the benefits:

✅ Fast scene transfer
✅ Restoration of modifiers and materials
✅ Cleanup of duplicates (e.g. Mesh.001, Material.002)
✅ Smart collection organization
✅ Console-style panel
✅ Clear and intuitive UI


C4D2Blender v1.1.0 - Changelog

🆕 New Features


🎨 Collection Color Tag

Added the ability to assign an identifying color to the import collection.

  • What it does: Allows setting a visual color to better organize collections in the outliner
  • How to use: Visual selector with 8 predefined colors (red, orange, yellow, green, blue, violet, pink, brown)
  • Benefit: Quick visual identification of imports in complex projects

🎯 Collection Selector

Added a smart selector for existing collections.

  • What it does: Allows selecting an existing collection using Blender's "eyedropper"
  • How to use: Click and select collection from the list
  • Benefit: Prevents typing errors and facilitates reuse of existing collections

🖼️ Import Objects with Viewport Colors

Added a button to control whether materials display their colors in the viewport.

  • What it does: Allows disabling the display of material colors in the viewport
  • How to use: "Apply color in viewport" checkbox (enabled by default)
  • Benefit: Cleaner, neutral viewport when working with many colorful materials

🔄 Material Refresh Button

Added a refresh button to apply material colors to viewport.

  • What it does: Automatically extracts colors from the "Base Color" of each Principled BSDF material
  • How to use: Button with 🔄 icon next to "Apply color in viewport"
  • Benefit: Allows updating viewport colors according to actual materials

🐛 Bug Fixes

🦴 Bone Import Issues

Fixed some problems related to armatures and bones.

  • Problem: Conflicts when importing skeletons from Cinema 4D
  • Solution: Improved armature handling during import process (not yet definitive solution)
  • Result: More stable import of rigged characters

👻 Render Hidden Objects

Completely solved the main problem with objects marked as "not visible in render" in Cinema 4D.

  • Problem: Imported objects appeared outside the collection with inconsistent visibility settings
  • Symptoms:
    • Objects outside the import collection
    • Objects hidden in viewport but visible in render
  • Solution: Automatic logic that detects and corrects the inconsistency
  • Result: Total consistency between Cinema 4D and Blender for render-hidden objects

📋 Summary of Changes

  • ✅ 4 new features for better organization and control
  • ✅ 2 critical bugs solved (bones and hidden objects)
  • ✅ More efficient workflow with fewer manual steps
  • ✅ Greater compatibility Cinema 4D ↔ Blender
  • ✅ More intuitive interface with visual controls

    🐛 Bug Fixes & Improvements

    📏 Corrected Import Scale

    Fixed a major issue where imported objects had an incorrect scale.

    • Problem: Objects imported from Cinema 4D were imported with a scale value of 0.01, requiring manual correction.
    • Solution: The addon now uses a global_scale of 1.0, ensuring that objects retain their original values.
    • Result: Imports now have a 1:1 scale, eliminating the need for manual adjustments.

    🔄 Fixed Default Rotation

    Addressed the incorrect default rotation of imported objects.

    • Problem: Objects exported from Cinema 4D with zero rotation would appear in Blender with a 90-degree rotation on one axis due to differences in the coordinate systems.
    • Solution: The importer now correctly configures the axis mapping (-Z, Y) during the import process.
    • Result: Objects now retain their original coordinates.

    ✨ Improved Re-import with Modifiers

    Enhanced the re-import process to better preserve modifiers added in Blender.

    • Problem: When re-importing a scene, modifiers added to objects in Blender were lost.
    • Solution: The addon now saves an object's modifier stack before a re-import and intelligently reapplies it to the new version of the object.
    • Result: A more non-destructive workflow, allowing users to add and retain Blender modifiers across multiple C4D2Blender imports.

    ⚠️ Duplicate Material Alert in Cinema 4D

    Added a preventive check for duplicate material names in the Cinema 4D plugin.

    • Problem: Blender struggles to handle FBX files that contain materials with identical names, leading to import errors or incorrect material assignments.
    • Solution: The Cinema 4D plugin now scans the scene for duplicate material names before exporting. If any are found, it displays an alert and cancels the export.
    • Result: Prevents data corruption and ensures a smoother import process by enforcing unique material names.

    📋 Summary of Changes

    • ✅ 4 major bugs/issues fixed for a more reliable workflow.
    • ✅ Improved import fidelity for scale and rotation.
    • ✅ Non-destructive modifier workflow on re-import.
    • ✅ Added pre-flight check in Cinema 4D to prevent common import errors.
    • ✅ Greater stability for the Cinema 4D ↔ Blender bridge.
