Facebook 3D Ready Cinema 4d Posts Using a free online converter to quickly turn .obj files into Facebook 3D Ready posts [10/03/2018]

What you will need

- Maxon Cinema 4D
- A 3D model
- A Facebook Account

Facebook recently announced their support for the new glTF 2.0 format. This means that we can now upload and share 3D ready model files that are hosted in a web viewer to our Facebook page. After learning about the format, and being a Cinema 4D user, I was excited to try making my own post, but found very little documentation and support on how to get a Facebook 3D ready post straight out of Cinema 4D. I was contacted by Maxon on their Twitter page after asking about their support for the new format. They directed me to this link which is definitely worth checking out if you're after a much more hands on approach, but for those of us who just want to get a quick 3D ready post converted and ready for Facebook, I found this method to be the most straight forward approach.

To start with, you need to have a ready made 3D model in Cinema 4D. You can texture the model as you wish, but there's currently limited support for the types of shading that the format can support, so choose to model and shade with this in mind.

Material support for the glTF 2.0 format Diffuse, Specular and Glossy material support. Other shader settings such as Luminance, Bump and Displacement doesn't seem to be supported just yet.

Once you have your 3D model, you will need to head to File -> Export -> and choose one of the model types, I chose Wavefront OBJ (.obj) since the converter I recommend for now support that file format.

You'll be given one or two files, depending on the settings you chose to export with. Next, you simply drag and drop the files into the online converter, which can be found here (Many thanks to these guys!). It will then give you a .glb file, which is glTF 2.0 compatible, and ready to be dragged and dropped into a Facebook post, just like any other standard media file.

The way we interface with media is changing a lot, and with more websites adopting 3D content, it will be interesting to see if there's a shift to pushing out more 3D ready media content. I'm almost certain that within a few months there will be a much better method for making web ready 3D media files, but figured I'd share this quick and dirty method in the hopes that more people experiment with it. Be sure to check out all of the documentation for learning more about the format and the support that's being rolled out for it.
