I want to reverse the mesh in the nif file in mod. I'm going to change this to righthanded bolt action. First, import the nif file in 3ds max, and then export it after reversing. After exporting, nifskope has opened the nif file which is reversed. Although the mesh has a certain reversal, You can see that the original (left bolt) and file format have changed. From here, a full-fledged question begins. As you can see, the left is the original and the right is the revision. The modified file is properly played in the game I know that you need to use a nipscope for finishing to work. To do this, right-click the file structure of the revision on the left. I need to make it the same as the original file structure. To do the same thing, try copy and edit string index I tried to touch it, but I do not know what to do.
