Does Rhino exported FBX file support Alpha Channel?

Hi, I am trying to set up some AR content from Rhino. I use a png file as the transparent material. It looks fine in Rhino. However, when it is exported as FBX, the transparency is not read correctly. That’s why I came up with the question in the title. First attached image shows what it looks like in Rhino. Second shows the exported FBX file.
