Default ThirdPerson can't crouch

Hey ThompsonN13, hi again.
Actually I don’t have time to create the animation so I downloaded the Animation Starter pack created for an FPS.
The continuos crash of Unreal it’s a mistery happened randomly when I touch some parameters of ThirdPersonCharacter.
Anyway I tried today in 10 minutes to add the crouch animation from that pack but wasn’t able because the skeleton meshes are different though the character are the same.
Could you share some infosor tutorials where is explained how to get animation from a char and bring it into an other one?
Thank you
