Exporting glass object into Adobe Aero

Hi everyone.

I'm having difficulties importing a 3D model that includes a glass sphere into Adobe Aero. I want to ask if there's a way to keep it transparent when exporting from Stager? 

Here's how I created my 3D model:

1. I created it in Nomad Sculpt

2. I used Adobe Substance 3D Painter to add the glass appearance to the sphere

3. Sent it to Stager. In Stager, I choose Export for Aero (and it was exported as a .GLB file)

4. I imported the .GLB file into Aero, but the glass material is gone.

Below are the actual result and my expectation:

I hope to receive your advice on this >_<
