How to add SOS to existing clothing using outfit studio?

[link00695]

Hello,

I am trying to add an SOS schlong to El Men's Underwear which I have converted to SSE and I am having trouble getting it to show in-game. Here are the steps that I have taken:

 

1. Open underwear_0.nif from El Men's Underwear in outfit studio
2. I drag and drop malegentials_0.nif from the SOS mod onto the underwear as shown below. I would like to modify the schlong so that it looks better, but for now I just want to get the schlong to actually show in-game.

Spoiler

3. I save the outfit to the underwear_0.nif file.

4. I repeat these steps for the underwear_1.nif file.

 

The in-game result is the following:

The schlong does not appear at all ingame. Instead, I just see the underwear as if the schlong didn't exist. I am a bit of a noob when it comes to bodyslide and I am not quite sure what I am doing to be honest. I would be very appreciative if anyone could help me figure out how to add a schlong to an outfit.
