Physics objects applied to character not immediately attaching to model

I am having an issue where any physics object welded to my character will not immediately attach and instead slowly move to the assigned constraint position.

  • manually setting position/cframe does not work, it will bug out the constraint
  • massless = true, anchored = false, cancollide = false on every part
  • i am welding the gun to the limbs, and the physics objects are welded to the gun

besides the character being forcefully moved when larger parts are used with physics constraints, this is an issue that i have not been able to solve because it is seemingly a sort of physics problem. is there any way to immediately put the physics objects in the desired position?
