How to permanently change the pivot of a static mesh?

[PinnaRandolf]

I found a solution, completely for free with few clicks, no Plugins or Addons needed:

1. Place the Mesh somewhere in your world
2. RightClick on your Mesh where you want to set the pivot and say “Set Pivot Offset Here”
   
   
3. Click on the newly set Pivot and say “Set As Pivot Offset”
   
   
4. Select the Mesh, go to the Details Tab, search for “Pivot” and copy those values
   
   
5. Open the Mesh in the Content Browser
6. Under Details you look for “Transform - Import Translation” and paste those values there
   
   
7. Now multiply every one of the values there by -1 (so 100 becomes -100 for example).
   You can simply add “*-1” in after the values and hit Enter, for each value.
8. Now “Reimport Base Mesh” (top left corner) and save.
   Done

You can now use “Reset Pivot Offset” on already placed Meshes for them to use the new Pivot.
