I dont know if the skeleton is the real issue here (before i’ve even begin im new on Unreal and animation stuff). So i tried to make an animation with a Character i made on Zbrush, then i rigged it on Blender an then import it into Unreal to animate it. (Maybe it is an important thing so when i import the 3D model it creates another bones that werent on the model in Blender) So when i started the animation i realized that my character got some deformation so weird, it creates an edge or something that only shows on the animation (without doing anything) and when you put the animation on the scene the deformation is still there. This deformation doesnt shows up on the skeleton window so i dont know what it can be and how to solve it. Thanks so much for your help.
