As of February 2018, Facebook offers the support for 3D posts via the glTF file format. Verge3D users may export content from 3ds Max or Blender and publish it live in their Facebook feeds.
Creating a 3D post on Facebook is straightforward: at first, you perform export in .glb format (.glb is the binary version of the glTF), and then drag and drop this file to your Facebook post composer. Below is the detailed breakdown.
To perform export in 3ds Max, go to the Verge3D menu and select "Export Facebook GLB...".
In the appeared file dialog, choose the export path and click Save.
To perform export in Blender, go to "File > Export" and select the "Facebook GLB (.glb)" option. The generic GLB-export option "Verge3D glTF Binary (.glb)" will also work but will produce slightly less optimized files.
Now you can just drag and drop the GLB file to your Facebook post.
In the Facebook post composer you can also choose the background to your liking.
Check it out how it looks on Facebook: link. The source file for this model can be found in your Verge3D installation inside the "applications" folder (see below in "Starter files").
We provide a sample Verge3D project that has been configured with the necessary export settings, for both 3ds Max and Blender. The starter project contains exactly the same environment map that is used by Facebook for maximum consistency.
It can be found inside the Verge3D distribution, located "applications/fb_max" (3ds Max) or "applications/fb" (Blender).
Here are some recommendations on how to keep your GLB file below 3 Mb yet to have decent graphics.
