BodySlide morph makes armor texture low-res

[Oijl]

I have a problem: meshes/mextures/Idon'tknowthedifference get messed up when I use BodySlide to fix the major boobage my character experiences when wearing the armor from the Triss Armor Retextured mod (http://www.nexusmods.com/skyrim/mods/4708/?).

It sounds a lot like this guy's problem, which he resolved, but his explanation was too advanced for me (also, he might have been having a different issue - and I'm making a new post because his is so old I don't want to resurrect it):

To recap, everything installs just fine and works as intended, but I want to make my character to retain her own bodyshape when she dons the Triss armor. So, I opened BodySlide, and, for example, selected "Ranger's Jerkin" from the dropdown option "Outfit/Body", checked the option "Build Morphs", then clicked "Build". This allowed me to alter her bodyshape with the RaceMenu in-game even while she's wearing the Ranger's Jerkin, but the Ranger's Jerkin looked as if it had become a very low resolution version of itself.

I have seen a lot of people in the comments section of the mod say that they've used BodySlide to give this Triss armor a breast reduction, but no one (that I've read) has mentioned the problem I'm having.

I'm using a CBBE body type.

Thanks to anyone who tries to help me, even though I am a random person on the internet and the only time I've ever posted here is when I needed help. Also, if you do respond, please remember that I am not a modder myself, so using BodySlide and Outfit Studio is challenging for me because I don't have a modding background, so please /do/ speak to me as if I am a child, because in as far as modding goes, I am.
