Quote -  So, does am I just out of luck and can't use it?

This is a classic case that shows how much easier is to do things right upfront instead of trying to retrofit products later. BTW, there is no need to do make any special shaders, just to have the right textures. Transparency maps are not needed because that property is built in the physical material. Get the right texture, plug it in the trasmission channel, you're done. Can be done in a couple of hours.

You have, as I have, now a good collection of vases that cab ne used with Reality, your best results, though, will be achieved with solid colors instead of textures.

BTW, this is a limit case, I used many textures with glass without doing much more than small adjustments. This is a classic case of faking results with shader tricks that are far detached from real world physics.

Anyway, good deal in communicating with the vendors, now they are aware of the limits of their approach and might do something else in the future. 

Cheers.
