I'm having a problem merging two elements with a subdivision surface modifier. The vertices are pretty well aligned, I think it has something to do with the subdivision surface modifier but I can't figure it out.
To be sure I was doing it the right way I hid everything but the two edge loops I want to merge and then aligned all the vertices one by one to have an exact copy. Everything looks good if I have the viewport on 0. The higher it goes the worse it gets. I don't know what to do to fix it.
I also tried to smooth it with the smooth tool but that didn't work either.
To be more expecific if I don't have the subdivision surface modifier everything looks just fine.
