Xandi, that was what I needed. It would help to know also if the alpha channel is set but here it is how it need to be set, so you change it if needed:

Alpha map: none. If you have an alpha map file erase it.

Alpha value: 1.0

 

Set the transmission color to 255,255,255 and change the gain for the transmission map from 1 to 2. See how it works. To change the gain click on the gear menu. 

Let us know :)
