Thank you all for the input :) I'm getting -some- image of how to use it from what you've explained me so far. So let me recap - if I want to use a custom body, I need to first build it in the app and then build it, making it default for all my bodies, right? Well, that can be done. The bigger issue I have is with the outfit I wanted to edit in the app. To be more specific - I wanted to adjust the chest piece from Witch of the Wild set. I wanted to adjust the tattoos and also mix it with different gloves and stockings, but they all disappear under outfit's body. I haven't found any information if it's body slide compatible, but it's not the newest armor, so I'm guessing it's not(?) @Teofa HDT body means high heels compatible? I'm not sure which one I'm using to be honest, I think it's HDT. I'd like to try to edit this outfit, but I'm afraid that if I mess things up I'll make my Skyrim even more unstable :P And just to be sure - does switching the armor to slot 49 by itself will remove the outfit's body? That's the first step I need to take before I jump into body slide.
