I guessed; I’m not with my own concepts, but I can usually translate and work with someone else’s pretty well.
I hope my directions came out well enough for you to work with them. I watched part of a youtube video on Magicavoxel’s transparency settings, which used water for the tutorial, and when he mentioned the light setting, it gave me the idea of “hiding” an inside brighter yellow with high light based settings, and an outside layer with a darker yellow and more roughness/refraction to give the final effect.
Helps I knew the idea of how it should look, my grandmother used lanterns like that in the barn a lot when I was a kid, and her old space heater had a similar look to it 
-edit-
Hmm, could ask @fantasyworm how he got the semi-transparent windows in the most recent update to his mod. Maybe see if the different means can be melded into a working final effect?
