Okay so Im using this old armor mod I used to use since Immersive Armors needs an update. But some of the armors are invisible, like the mesh isnt loading, I noticed this on some other armor mods too. I get this issue sometimes and IME it's a conflict between armor mods and body textures. Like the khajiit/argonian claws and feet mods with non vanilla indexed armor items. Same thing happens to sheilds on back mod with sheild retextures. So I'd start by testing special race, skin textures and armor mods.
There are now 2 main files to choose from, one with large bigger max breastsize and breast physics and one that is the same as the original release (no physics, shorter sliderrange for breasts).
There is now an alternative version for those who want bigger brest and breast physics.
Pictures and clip coming soon.
