Hello, I have been trying to fix neck seams I am getting using SG Textures Renewal UNP (there could possibly be other mods contributing to the seam). I want to use the Caliente Texture Blender to fix the seam but I just cannot work it out after an hour of trying and googling. It was very easy to use back when I used NMM but I can't work it out with Mod Organizer. I have tried opening the blender in Mod Organizer and still no source textures are available. Does anyone know how to do it? (preferably step by step because I'm new to Mod Organizer). Thanks :)
