I have deformed bones when rotating

Hello guys

i’m having this problem with every skeletal mesh i create and rig bones, everytime i rotate something it starts deforming the mesh. It also happens on blender (where i origiinally created the mesh) i think i tried a lot of thing, but i think i’m missing something. It have enough subdivision, more than 300,000 triangles, and i tried smooth it, but it doesn’t solve :frowning:

i’m having this art project and i’m creating some meshes and making it audio reactive, but this happens and is really frustating.

any help?
