Moving parts of a custom character without using animations

I am working on a custom character for my current project. Due to the way the custom character is built, I can not create a rig and use animations. Instead, I need to use an alternative method of moving the character’s hands.

What I have tried:

  1. Tweening (Won’t work because the hands are welded and unanchored
  2. CFrame (Won’t work because of the welds

How the character model is set up:
The character model is pretty basic. I have a torso, which also doubles as the player’s head, and HumanoidRootPart. Then I have 2 hands in the front of the player. The hands have the main part that is welded to the torso and some detail that is welded to the hand’s main part. Everything is unanchored except for the torso.

Specifics of what I am trying to do:
I am trying to move the main part of the hand 1 stud on the Z axis.

Change the C0 property of motors/welds in your parts.

It’s better to just properly rig it and use animations.

Wouldn’t be practical because of how it is set up.

And why wouldn’t it be practical?

Because the character doesn’t have legs or arms
