ElizaKzi Unfortunately, it is quite hard to give a clear answer to this. The spine-ue4 runtime is based on the generic spine-cpp runtime, and so far the spine-cpp runtime has not finished adding support for physics constraints. Therefore, it should be necessary to add support for physics constraints in spine-cpp first, so it is not clear at this time how long it will take to add it to spine-ue4 after that.
