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.
In the appeared file dialog, choose the export path and click Save.
从Blender导出GLB（Export GLB from Blender）
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.
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.
