I'm trying to show a 3D model on Facebook and display its edges and lines. I found that I could export a 3D model from Sketchup using glTF Export plugin to a glb file that I can drag and drop in a Facebook post.
I tried many ways to set material, width, styles on lines in my model but once imported in Facebook the lines don't appear. It's not a Facebook problem since the gtTF viewer has the same display. I also have the same rendering problem by ubloading an stl file to Sketchfab.
Is there a missing implementation in glTF format?
Is there another freeware to export a 3D model to Facebook (showing edges)?
