Since there is updated KHR_materials_translucency spec need to update Babylon implementation.
KhronosGroup:main ← DassaultSystemes-Technology:KHR_materials_translucency
opened 09:26AM - 10 Jun 20 UTC
An extension for the metallic-roughness material that adds a translucency effect… , i.e., a diffuse lobe on the back-side of the surface. This is useful
* for thin materials like leaves or paper
* for volumetric materials like plastic or candle wax; in combination with `KHR_materials_volume` (#1726) in case of SSS with short scattering distance
Welcome aboard!
I’m not sure this extension is planned at the time, it’s kind of paused on Khronos side, see this comment:

@zeux That's a great question. I would like to see this extension ratified most… ly as-is, but it may not happen soon. I've re-started the discussions on the Khronos PBR TSG calls, but I can't guarantee it will suddenly move forward. There are an assortment of concerns ranging from performance to interoperability to consistency between engines. If you know of some solid use cases or sample models that we could use as fuel for the burning desire for this, please let me know.
cc @bghgary , in case he has more information.

We have talked about this one recently in the WG but it’s probably still a ways away from being ratified. Updating this code in Babylon is pretty straight forward if anyone needs it. Feel free to create a PR to update it.
