I need some advise regarding transmission maps and thickness maps.
polycounter lvl 4
I understand the 'concept' of thickness maps.
however I cant find any clear documentation explaining how to use transmission maps or thickness maps. I have looked through the polycount wiki.
recently I made a paper lanten, I used emission maps...

however originally I wanted to make a very thin paper with an candle mesh emitting light inside the lanten mesh, I was told that transmission maps would be appropriate for this.
however Im not sure how to use them. are they grayscale or rgb?
if I add a transmission output node in SD, I notice no change to the rendered substance.

If I export this as a sbsar to Substance Painter, and add an new channel in SP (transmission) what else should do I do? to make it work etc?
(thank you for time!)
