Specifically, “ADOBE_materials_thin_transparency”
According to this README, there are folks working on this at Adobe and Microsoft but I don’t see it anywhere in the code. Is it possible?
Thanks!
Hiya A. I have no answer for that, but I found something possibly interesting:
I don’t understand very much about exporting advanced materials, but I DO understand part of the caption for the LAST picture on that page: “Simple implementation using Babylon.js engine. This implementation uses the mip levels of the captured opaque scene to approximate scattering of transmitted light.”
Me, I would find this Mike Bond chap… and trade him a bucket of chicken… for his BJS folder from his hard drive. 
At minimum, scratch his belly until he starts talking.
Stay tuned for other/wiser comments… hopefully coming soon. And if you DO speak-with Mr. Bond, and/or get some cool custom BJS scenes from his BJS folder… do share, eh? THX!

Great advice! I’ve reached out to him and will report back if I hear anything. If there has already been work done for this, I’d love to try and help get it merged into Babylon.

I heard back from Mike Bond. Here is his experimental repo.
He pointed out that Khronos is working on approval of an official extension to handle transparencies:
Hopefully folks like @Deltakosh can help guide the Babylon side of things. This would be a KILLER feature.
