glTF glass

Does anyone know how get glass to export when exporting a glTF model. Everything else comes out fine except my glass is missing?

Do you have some screenshots?
Do you have geometry and it is not transparent, or you do not have the geometry or is it too transparent?

The plugin has some limitation when the material shader uses some specific functions or some specific shading models.
But, anyway, you should get some kind of material on your glass part.
More info on the material export here

I have geo inside UE5. Its all one piece, the body of the aircraft and the glass. When I export it out the geo for the glass does not show up, its missing.
I have a feeling my glass material is to complex?

can you share the glTF file with me?

Unfortunately I can not share the file due to restrictions at work. I’m sorry.

Do you get any warning/errors?
Can you share the glass material with me then so i apply it on another geometry and try to export?

I actually just made a very simple glass material and it fixed the issue. My hunch was the UE5 glass material I originally made was way to involved for the export. You can see how the mesh is actually showing up in the wireframe vs the wireframe earlier.
