Expert Help Wanted: Specifically to help edit my glass' properties

Hi there!

I'm self-taught with Stager and am flailing (and failing) to properly edit my model's glass material properties, to match whiat its rendered PDF looks like when exported as a GLB for web page viewing. Just everything about my final GLB is a bit "off" and I cannot seem to edit the properties to look as good as the PDF render. (I understand that the lighting reflections will be from different angles, as glTF Viewer doesn't have the exact same light positionings in its online demo environment.)

If you're someone that knows Stager well, and can help me to accomplish this... can you send me a message? I'm happy to pay you for your time. I've looked for experts on Reddit, Upwork, Fiverr, etc. and nobody really seems to be proficient in Stager (as opposed to Blender, Maya, etc.) and I have struck out finding help on those websites and others.

Thank you!
