Having issues with the rig

So we are trying to replace the player’s StarterCharacter with this rig but anytime we insert this rig with roblox’s default animation script the animations don’t play (AT ALL) even after customizing the script and animations in the default Animate script (we have custom animations we would like to play). One thing we’ve noticed is that the animations play on the AnimationController’s Animator but with the Humanoid’s Animator it doesn’t work and anytime we tried playing the animation with both in the rig it just doesn’t work at all.

The animations are published under the group and have the correct Animation Priorities as well.

Here’s the setup: (Don’t worry anytime we test it we make sure to put it under StarterPlayer as StarterCharacter)

Any help would be appreciated

The problem is that Roblox edits StarterCharacter internally, the only way to prevent it is to make your own character loading system.
Etc. Plr.Character = char

To do this, you must disable character auto-loads in Player service.
