So I've been working on my Vivec replacer lately, and I've been making progress. I have the asymmetrical BB meshes downloaded and I made Dunmer/Chimer textures for them specific to Vivec, the problem is I can't seem to figure out how to make them replace Vivec's body in the existing mesh. I tried importing them into Blender but Blender straight up can't import them for some reason, and I tried importing the individual bodyparts into Nifscope on top of the appropriate parent nodes, but they wouldn't copy over. The furthest I got is copying the entire body into the Vivec creature mesh, only binded to it's own skeleton, which is kind of useless.

I don't have the files for the mod available to upload at the moment, but if anyone would know how to do this for me, I'd upload it as soon as I can, and greatly appreciate it. Otherwise, does anyone know how I can make this work?

I'm also planning on making two versions, one with the male BB mesh and the other with the female. These two will both have unique loincloths and the female version will have a bra as well. I plan to base the clothing mesh off of the "outfit" mesh in Plankye's Almalexia replacer (remade from scratch of course), but I also have no idea how to bind such an outfit to the creature skeleton. I mean, I'm capable of doing all the modeling and texturing work, I just haven't the slightest clue how to actually make it function ingame as a replacer. Could someone please help me out? Thanks in advance.

In NifSkope, instead of copying them to the "parent node" copy them to the "scene root" node (probably named Vivec.nif or something at the top of the list). Change/Rename the Vivec.blahblah node to Scene Root and you should be able to copy the body parts into the .nif now (hope this made sense and is helpful).
