This section details how to work with CINEMA 4D and Viz Artist.

The CINEMA 4D and Viz Artist integration imports complete geometries, lights, and animations, from CINEMA 4D to Viz Artist. Viz Artist imports scenes from CINEMA 4D without the need for a local installation of CINEMA 4D on the Viz Artist workstation. 3D objects are imported either as their direct primitive object counterpart in Viz Artist, or as meshes. 

Viz Artist integrates a CINEMA 4D LiveLink tool that lets you make changes to a scene in CINEMA 4D. When Viz Artist is in On Air Mode, it updates live based on your changes. The CINEMA 4D LiveLink tool is able to update the position, rotation and scaling properties of all objects in a Scene.

IMPORTANT! The license required for the import of CINEMA 4D Scenes is issued by Vizrt.

This section contains the following topics:

System Requirements and Configuration

To Enable Correct File Format

To make sure that CINEMA 4D saves all the information Viz Artist requires when importing from .c4d files, enable the following settings in CINEMA 4D’s preferences.

Cinema 4D R15-R20

  1. Open CINEMA 4D.

  2. Choose Edit > Preferences > Files.

  3. Check the Save Polygons for Melange checkbox. If required, check the Save Animation for Melange checkbox. This setting generates Key Frames for animations that CINEMA 4D’s MoGraph toolset produces, by baking the key frames into the timeline. This can have a performance impact when playing out the scene in Viz Artist.

Cinema 4D R21

  1. Open CINEMA 4D.

  2. Choose Edit > Preferences > Files.

  3. Check the Save Polygons for Cineware checkbox. If required, check the Save Animation for Cineware checkbox. This setting generates Key Frames for animations that CINEMA 4D’s MoGraph toolset produces, by baking the key frames into the timeline. This can have a performance impact when playing out the scene in Viz Artist.

Cinema 4D R23 or Later

  1. Open CINEMA 4D.

  2. Choose Edit > Project Settings.

  3. Switch to the Cineware Tab.

  4. Check the Save Polygons Cache checkbox. If required, check the Save Animation Cache checkbox. 

Cinema4D Substance FBX Workflow

Starting with Viz Engine version 5.0, Viz Engine is capable of importing FBX files with Substance surfaces and translates them to our PBR rendering. You can use all your existing Substances in your Cinema4D, export as an FBX file and import them afterwards as Scene in the Viz Engine Render Pipeline of Viz Engine 5 or later.

  • Create or load your Cinema4D project.

  • In Extensions > Substance Engine, load your SBAR file.

  • This imports your SBAR file(s):

  • All of these materials can now be used on your geometries by dragging and dropping them onto your meshes.

  • Select Export > FBX:

  • Make sure, that Substance is selected.

  • Save the file as FBX as seen in the screenshot above.

  • Switch to Viz Artist and go to Import and select Scenes. Your FBX is imported as a standalone scene.

    • When importing, make sure you select Viz Engine as target pipeline.

    • Once the import has finished, open the scene. Your substance textures have been mapped correctly to a newly created PBR material in Viz Engine, the textures are also added to Workspace area:

Modifying Substance Settings

Once you imported your Substance files into Viz Engine, they show up in the Workspace Area:

Double clicking on one of the Workspace items opens the exposed settings:

To install CINEMA 4D LiveLink, you must first install CINEMA 4D. The Viz Artist installation files include the CINEMA 4D LiveLink tool, but it is not selected for installation by default.

To Install CINEMA 4D LiveLink During Viz Artist Installation

  • For Cinema 4D R20 or newer.

    • Complete the Viz Engine Installation.

    • There is a prompt at the end of the installation reminding the user to manually add the plug-ins.

    • Install CIMEMA 4D.

To Install CINEMA 4D LiveLink to an Existing Viz Artist Installation

Compatibility: These steps are only compatible for CINEMA 4D R20 or older. See https://www.plugins4d.com/installing

  1. Install CINEMA 4D.

  2. Start the Viz Artist installation in Repair Mode. The Viz Artist installer looks for the CINEMA 4D installation folder, and copies the LiveLink files to the CINEMA 4D plug-in folder.

Example: C:\Program Files\MAXON\CINEMA 4D R17\plugins\vizrt-live-link

After installing the LiveLink files, they remain in the CINEMA 4D installation folder even if you remove the LiveLink feature later on.

Troubleshooting CINEMA 4D LiveLink Installation

If the installation displays the CINEMA 4D LiveLink will not work warning, check the following possible solutions:

  • The Cinema 4D installation location is not the default folder.

    • Manually copy the LiveLink files to the Cinema 4D plug-in folder.

    • The LiveLink files are in the Viz Engine installation folder: <viz install folder>\CINEMA 4D LiveLink\[R15|R17|R23]\vizrt-live-link.

  • CINEMA 4D has not been installed prior to Viz Artist installation.

    • Complete the Viz Engine installation.

    • Install CINEMA 4D.

    • Start the Viz Artist installer again and select Repair mode. This makes a copy of the LiveLink files to the CINEMA 4D plug-in folder.

  • For Cinema 4D R20 or newer:

    • Complete the Viz Engine installation.

    • Install Cinema 4D.

IMPORTANT! Open the same files in Viz Artist and CINEMA 4D. Because Viz Artist and CINEMA 4D communicate using UUIDs, opening different file versions causes the live link to fail.

  1. Open Viz Artist and CINEMA 4D.

  2. Import the project in Viz Artist (Import, Import Scene).

Note: Cinema4D import works for the Classic Render Pipeline only.

  1. Set Viz Artist to On Air Mode.

  2. In CINEMA 4D:

    1. Click on any entry in the CINEMA 4D Scene Tree.

      image-20240917-124442.png
    2. In the Basic Panel, click on Enable.

    3. Enter the Viz Artist/Engine Host name.

    4. Enter the Viz Artist/Engine Port number.

    5. Click on Reconnect.

    6. The Tag properties panel always shows the current connection status.

Changes made to the scene in CINEMA 4D now reflects automatically in the scene in Viz Engine. The Live Link works only one way, from CINEMA 4D to Viz Artist. Moving objects in Viz Artist does not transfer back to CINEMA 4D.
