[Help] Custom body slightly misaligned

[AciesGecko]

Hello, I have an issue that is driving me mad, and I have no idea how to solve.

I'm trying to edit some bodies and when trying them in-game, the body is always slightly misaligned.

For example:
I imported Type4 body into 3dsmax to reduce the breast size. Then I export it to .nif and this is the result:

You can see the body is misaligned from beck and from the wrists as well.

I tried everything I could come up with to fix this, but nothing has been working so far.

I use 3dsmax 2016 with nif plugin, but reducing the breasts makes the skin modifier break so I have to copy bone weights again. I checked a hundred times so the weights are identical but the gap still happens. Here's my export settings (I also tried several settings and everything gives me the same result):

I also tried copying the weights with outfit studio, the body is aligned with the neck and hands on outfit studio, I copy the bone weights, then load into the game, and the result is the same: misaligned neck and hands. I honestly have no idea how to fix this.

 

I checked the .nif on nifskope so it's identical to the original body asides from the smaller breasts. I thought maybe it was misaligned here, but it's not either (I think?) everything seems centered:

Then I thought maybe I was messing up with the export settings on 3dsmax, so I tried exporting an .obj and using outfit studio to turn it into a .nif. Same misalignment, with .fbx same thing occurs.

 

I also tried this on the Robert S body because I can't add armor with the penis hanging there so I cut it (lol) and I also get these misalignment:

Here's how it looks with the unmodified body (no neck seam at all):

Edit: Solved it after days of trying different things. If someone in the future encounters the same trouble, here's the fix:

With 3dsmax, exporting as .nif is impossible to fix for me. It has to be done as .obj, I had enabled optimize vertex, normals and textures. Don't enable that and you'll have perfect mesh!
