Exporting materials out of UE4 (4.27) as GLBs

Long story longer; I am wanting to take Revit models, export them to Twinmotion, import the twinmotion file into UE4 and export the UE4 file out as a GLB file.

I have clients who are wanting to own the 3d model of their house as an NFT. I own a seat for Twinmotion and am fairly familiar with its operations, I have been able to import their Twinmotion file into UE4 (4.27) in an Archviz format.

I have downloaded the plugin for the GLTF exporter so I can export the file out as a GLB format but am confronted with multiple errors referencing materials upon export. The GLB file is created but will not open in any GLB or GLTF 3d viewers.

I feel like I am missing a significant step dealing with materials lol!. I am admitedly very new to the Unreal environment and possibly missing something there.

I have also postulated that it could be in the model prep either out of Revit or out of twinmotion. There is not a lot of documentation out there but it has clearly been done before (see Mars house). Any thoughts?

What kind or errors do you get?
Did you look at the documentation on the export? Box
Material baking can be complicated.

2 pieces of information:

  • twinmotion is working into adding gltf export
  • we are going to upgrade the gltf exporter marketplace plugin.
