Help using LR Studio to create new costume

[goldarmor92]

I'm trying to change one of FunnyBunny666's costumes, "MAI DOAXVV MOONLIGHT SHADOW" using LR studio and nothing I try seems to work.  Basically, I want to delete some of the clothes and replace the default body underneath (which has gaps and missing textures) to the "Real Nude body."  The software will let me add both at the same time and I can see exactly the result I want but it won't let me combine the TMCs.  So I did some digging to figure out how I'm supposed to do it.  It seems I must create a tmcmesh of the nude body and use TMC polygon inserter to combine the tmcmesh with the TMC of the edited costume.  However, this gives me some messed up textures and definitely isn't the nude body I supposedly swapped.  I tried a different character with a different edited outfit (Leifang Brilliant Colors also by FunnyBunny666) yet I got a similar error with a messed up nude body in the result.  I'll attach and image of what I intend to get vs. what I'm getting.  Please help me if you have the time, I'd love for this problem to be solved.  Any help would be greatly appreciated

you need to swap the texture also. right click the skin and select texture viwer. on top right corner click swap and select the texture. you can extract texture from the same place you are getting your body from. there are usually 4 textures for the skin. just to be safe replace all of them. you can view these from drop down menu on top left corner
