I found my issue, maybe it will help. My problem started when I switched from NMM to MO. What my issue was, was that some armors are packed different. I went through all my invisible armor mods and saw they were packed with a data file, which contained the .esp, the meshes, and the textures. While MO says it looks good if you only pull the .esp out, you need to pull everything out of the data file and then delete the data file, MO doesn't seem to recognize the data file contains the meshes and textures. This helped me, but I'm new to MO, so many of you may already know this. I hope this helps some people.
