How can I resize an npc while keeping motor6d?

I want to achieve resizing an npc and still being able to animate it. The issue is that whenever I resize an npc’s bodyparts, all the motor6d gets removed. Is there a trick or quicker way to add motor6d to resized npcs.

i use this plugin to instantly rig without auto position change

here if you want Constraint Editor - Roblox

TO USE THIS PLUGINS

  1. Select Part0 or main part first
  2. Select Part1 or the rest of part you want to animate
  3. Click on “Create Motor6D” (DO NOT DESELECT)

it will rig with just one click without adding Motor6D again
