ProPivot modifier package is an editor utility that lets you modify your pivot points that come from any 3rd party modeling software and re-organize them so you can work with the pivots correctly instead using the "hack" of adding Empty GameObjects to organize the pivot orientation of your meshes. Pivots can be rotated, moved and centered by average or bounding box.
Rotate: Rotates the selected mesh around the global axis of the pivot.
Move: Moves the selected mesh around the selected pivot.
Average Center: Finds the average center of all the vertexes and moves the mesh around the average center where the pivot gets placed
Bounding Box Center: Centers the pivot around the bounding box of the mesh.
WARNING: This tool will not work with generated primitives. and minimum version to run it is 4.3 as the new Undo system came out.
