If you're a 3D artist using Cinema 4D for your modeling projects, you may need to export your work to other platforms or software that support the OBJ file format. Here's a step-by-step guide on how to export OBJ from C4D:

1. Open your project in Cinema 4D and make sure all the objects and materials are in place.

2. Select the objects you want to export by clicking on them in the Object Manager or the 3D viewport.

3. Once you've selected the objects, go to File > Export > Wavefront (.obj) to open the export settings.

4. In the export settings, you can choose the location where you want to save the OBJ file and rename it if needed.

5. You can also adjust the export settings such as scale, polygon triangulation, material options, and grouping options to customize the OBJ export according to your requirements.

6. After setting up the export options, click 'OK' to export the selected objects as an OBJ file.

7. Your OBJ file is now ready to be used in other 3D software or platforms that support the OBJ format.

Keep in mind that when exporting OBJ files from Cinema 4D, you should consider the compatibility of materials, textures, and geometry with the targeted software or platform. It's recommended to do a test import of the OBJ file in the target software to ensure everything looks as expected.

Exporting OBJ files from Cinema 4D is a straightforward process that allows you to seamlessly transfer your 3D models to other software and platforms. By following these steps, you can ensure that your OBJ exports from C4D are optimized for further use, whether it's for rendering, animation, or interactive applications.

In conclusion, exporting OBJ from Cinema 4D is an essential skill for 3D artists and designers working on cross-platform projects. With the right export settings and considerations for compatibility, you can leverage the flexibility of the OBJ format to collaborate and integrate your 3D models across different workflows and pipelines.
