How do I go about converting them? I apologize, I'm a total noob to this, hahaha.

I'm using a texture replacer for most of the clothing and have used the NIF optimizer and still no dice. I'm pretty sure I'm doing something wrong, but I can't figure out what.

Sorry to double-post, but this is what happens when the hands mod is disabled. Gloves and whatnot cover the seam, but I can't figure out what I'm doing wrong. I've used the NIF optimizer and everything.

Like the title says, I'm getting massive wrist gaps if I extend the slider too far. I have SAM Light 1.3 installed and proper in my load order and I attempted to use the SAM Hands Fix, but that does not really seem to do anything at all, unfortunately. It just makes the hand tiny while the rest of the body chunks out. Any solutions on how to fix this? Images enclosed below of results.
