I can’t figure out how to do this in Unreal Engine 4. I could only find a tutorial on it for UDK UDK Tutorial Part 123: Physics- Softbody - YouTube
If anyone could show me some kind of Soft Body tutorial for Unreal Engine 4 it would help a lot.
NVIDIA removed generic soft bodies from PhysX 3.x and focused on cloth simulation with APEX. UDK probably uses PhysX 2.x in which soft bodies were still a thing. You will need a custom implementation of soft bodies for UE4 and PhysX 3.x.
