I have the hipheight at 0, and also, the rig is a normal invisble r6 rig underneath. It seems to be something else, since im always having my NPCs with a hipheight of 0 and experiencing no issues.
Well, prior to this, chenging the hip height would ether make the NPC float higher, or be lower in the ground. However, none of these changes fixed the stiffness in the animation, as well as the wobbling.
Well I doubt you were animating the HumRoot so I’m gonna assume that maybe the WeldConstraits are off or something, not really sure if the welds “Parts” will actually affect anything but I usually have them as Part0 = MainPart and Part1 = OtherPart
Also check if the “OtherPart” is welded to a different part that could maybe be welded to another different part that is moving
You mentioned that you were using an invisible R6 rig. I’m assuming you’re using the R6 rig to move it around, could you try removing the Rig and just having the Monster as the Humanoid?
The monster model is a folder in the R6 rig named CharacterModel.
The HumanoidRootPart has a joint that connects to the LowerTorso. (LowerTorso is a part in the CharacterModel)
I noticed that the animation itself is not stiff. Its mostly the LowerTorso part. It does not move much.
