Author Topic: advice for workflow of 'transmission output' and/or thickness maps  (Read 1269 times)

I understand the concept of thickness maps.

however I cant find any clear documentation explaining how to use transmission maps or thickness maps.

for example.

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?
