C4D to XPression Key Frame File Workflow Kit

A practical workflow package for using Cinema 4D Camera / Object keyframe motion data inside XPression as Key Frame File.

This package is designed for users who want to bring Camera / Object motion created in Cinema 4D into XPression, export it as Key Frame File txt data, assign it to XPression parameters, and use it as part of an XPression scene workflow.

This package includes a Cinema 4D sample scene, Cinema 4D Python exporter, Camera/Object txt samples, an XPression sample project with Key Frame File already applied, README files, and workflow guides.

Instead of directly copying Cinema 4D Position / Rotation / FOV values into XPression, this package provides a practical workflow for converting C4D motion into Key Frame File format and checking the required settings on the XPression side.

Target Users

This product is intended for users who:

• Want to use Camera / Object motion from C4D inside XPression

• Want to reproduce C4D camera work in XPression through Key Frame File

• Want to use C4D keyframe motion data as XPression Key Frame File

• Want to check Source Column assignment with a practical sample

• Have experienced mismatches when copying C4D Position / Rotation / FOV directly

• Need to understand Right Handed Coordinates or Rotation Order in XPression

• Want to separate conversion issues from scene-structure issues

• Want to use practical sample files as a reference for their own XPression workflow

Basic Workflow

1. Open the C4D sample

Open XPression Key Frame File exporter_Sample.c4d in Cinema 4D.

2. Run the Python exporter

Open Script Manager in Cinema 4D and load the included Python file using Open Script...

File to use:

XPression Key Frame File exporter.py

Select only one Camera or Object, then press Execute in Script Manager to export the txt file.

3. Check the txt file

If a Camera is exported, the txt file uses a 10-column structure including FOV.

If an Object is exported, the txt file uses a 9-column structure including Position, Rotation, and Scaling.

Check Type, Rows, column number list, and first row in the Cinema 4D Console.

4. Load the txt in XPression

Load the txt file as Key Frame File in XPression.

Assign the Camera txt to the Camera.

Assign the Object txt to the Object.

5. Check Key Frame File settings

In XPression, check the following:

• Column Delimiter = Tab

• Decimal Separator = Dot

• Right Handed Coordinates = OFF

• Rotation Order = default

• Source Column = Match the txt column number

• Scale = 1.0

• Offset = 0.0

6. Adjust screen placement with the parent Group

In this sample, the Object driven by Key Frame File is placed inside a Group, and screen-position adjustment is handled by the parent Group.

By separating C4D Position / Rotation / FOV data from final XPression screen placement, it becomes easier to avoid double correction and troubleshoot offsets.

XPression Screen Coordinate Notes

In XPression, when working with screen coordinates, 0,0 is based at the lower-left of the screen.

For a 1920×1080 XPression scene, the screen center is 960,540.

If C4D data built around the world origin needs to be placed at the XPression screen center, check parent Group offset and Global Transformations.

This screen-center offset is a separate issue from Position / Rotation / FOV conversion.

Conversion Concepts Used in This Product

Position

C4D X/Y values are used as-is, while Z is inverted.

Example:

C4D Position

100 / 200 / 300

Key Frame File Position

100 / 200 / -300

Rotation

C4D HPB values are not copied directly into XPression Rotation X/Y/Z.

The Python exporter reconstructs the C4D orientation as a matrix and converts it into Rotation X/Y/Z values that can be used in XPression.

FOV

This workflow assumes a Perspective Camera and uses Cinema 4D vertical FOV.

For Camera txt, FOV is column 10.

Important Notes

This product is a practical workflow package for using C4D Camera / Object motion inside XPression through Key Frame File.

Before using it as part of a production template, always test it in your own environment.

No video tutorial is included in v1.0. Please refer to README_JP / README_EN and WORKFLOW_GUIDE_JP / WORKFLOW_GUIDE_EN for setup and workflow instructions.

Results may vary depending on:

• XPression version

• Cinema 4D version

• OS environment

• GPU / driver environment

• Frame rate

• Scene resolution

• Rotation Order

• Right Handed Coordinates

• Source Column settings

• Scale / Offset

• Parent Group

• Global Transformations

• Camera FOV

• txt file path

• Output environment

If you open the XPression project on another PC or from another folder, the Key Frame File txt references may be broken.

If this happens, manually reassign Camera Sample.txt and Cube Sample.txt.

C4D to XPression Key Frame File Workflow Kit

This is a practical workflow package for using Cinema 4D Camera / Object keyframe motion data as XPression Key Frame Files.

Instead of directly copying Position / Rotation / FOV motion created in C4D into XPression, this package includes a complete set of samples for exporting it as Key Frame File TXT, assigning it to Camera or Object parameters in XPression, and using it as part of an XPression scene workflow.

This package includes a C4D sample scene, a Cinema 4D Python exporter, Camera/Object TXT samples, an XPression sample project with Key Frame Files already applied, a README, and workflow guides.

This is not a finished production template, but a practical package that consolidates the conversion, export, assignment, and verification steps for using C4D Camera / Object motion as XPression Key Frame Files.

Instead of directly inputting C4D Position / Rotation / FOV values into XPression, you can use the actual samples to confirm how to convert it for Key Frame Files, which columns to assign to which parameters in XPression, and the order in which to check Right Handed Coordinates, Source Column, Scale / Offset, Rotation Order, Parent Group, and Global Transformations.

Target Users

This product is suitable for those who:

• Want to handle C4D-derived Camera / Object motion in XPression

• Want to reproduce camera work created in C4D in XPression

• Want to use C4D keyframe data as XPression Key Frame Files

• Want to check Key Frame File's Source Column settings with practical examples

• Have experienced discrepancies when directly inputting C4D's Position / Rotation / FOV

• Have been confused by XPression's Right Handed Coordinates or Rotation Order

• Want to differentiate between conversion issues and scene structure issues between C4D and XPression

• Want to check how to apply XPression in their own environment while looking at practical samples

Basic Usage

1. Open C4D sample

Open XPression Key Frame File exporter_Sample.c4d in Cinema 4D.

2. Execute Python exporter

Open Cinema 4D's Script Manager and load the included Python file using Open Script...

File to use:

XPression Key Frame File exporter.py

Select only one Camera or Object, then press Execute on the Script Manager to export the txt file.

3. Check the txt file

If a Camera is exported, it will have 10 columns including FOV.

If an Object is exported, it will have 9 columns including Position, Rotation, and Scaling.

In the Cinema 4D Console, check the Type, Rows, a list of column numbers, and the first row.

4. Import into XPression

Import the txt file as a Key Frame File in XPression.

Assign the Camera txt file to the Camera.

Assign the Object txt file to the Object.

5. Check Key Frame File settings

In XPression, check the following settings:

• Column Delimiter = Tab

• Decimal Separator = Dot

• Right Handed Coordinates = OFF

• Rotation Order = default

• Source Column = Match the column number in the txt file

• Scale = 1.0

• Offset = 0.0

6. Adjust the position on the screen with the parent Group

In this example, Objects driven by Key Frame Files are placed within a Group, and the screen positioning is handled by the parent Group.

By treating the Position / Rotation / FOV values from C4D and the screen positioning adjustments in XPression separately, it becomes easier to reduce double corrections and unexplained discrepancies.

About XPression's Screen Reference

In XPression, when treating screen coordinates, 0,0 is the bottom-left origin.

In a 1920x1080 XPression scene, the screen center is 960,540.

If you need to center data created around the world origin in C4D to the screen center in XPression, check the center offset in the parent Group or Global Transformations.

This center offset is a separate consideration from the Position / Rotation / FOV transformation conventions.

Transformation Concepts in This Product

Position

C4D's X/Y are used as is, and only Z's sign is inverted.

Example:

C4D Position

100 / 200 / 300

Key Frame File Position

100 / 200 / -300

Rotation

C4D's HPB is not copied directly to XPression's Rotation X/Y/Z.

The C4D orientation is reconstructed as a matrix within the Python exporter and converted to Rotation X/Y/Z that can be handled in XPression.

FOV

Assuming a Perspective Camera, C4D's vertical FOV is used.

For Camera txt files, FOV is in the 10th column.
