The easiest way is to extract the BMP with FSHx and open it in Photoshop.
Select the face layer and add a layer mask to it.
Then go to the channels tab and select the layer mask channel.
Open one of the sweat alpha files in photoshop, select all (CTRL+A), and copy then paste it into the layer mask channel.
The face will become transparent if you did it correctly.
Then save it as a PNG image.
Open FSHx, open the cyberface fsh, choose import, and browse to where the PNG file was saved.
Notice that the PNG file will not show up in the window.
Click on the text box and type "*.png" without quotes and your png file should show up.
Select it and click OK, and you should have then have the "blue film" on the cyberface.
