Are there a lot of smooth animations for close combat? Starting from hand-to-hand combat and melee weapons, I watched a lot of examples, but they are all some sharp, little smoothness, of course, there is a mocap, but still, it is expensive for indie developers, there is also a rokoko animation Library but there is little melee animation at the moment, perhaps this situation will change with the advent of unreal engine 5, full Body IK, and other animation chips, in the next 5 years.
