Transparency Alpha issues

[drvoxxx]

Hi,

I'm having issues with transparency on model viewer.

It loads the model correctly but once i rotate it i have issues with the transparency.
Please see screenshots here.

The model was exported in GBL format in substance painter. The diffuse map is looking correct in photoshop when i see the alpha, glass has transparency.

Anyone have a clue of what's happening?

Thank you,
Pat

Solved, i had all in a single object. Now i switched glass to a separate object and its working fine.
