Body instances

Hello,

I wanted to ask if someone could tell me what are BodyInstances. I am trying to find answer for 2 days without exact answer. I was chcecking out the Rolling game in C++ and they are using forces on BodyInstances however I couldn’t find anything in docs about it since in code it is member of uStaticMeshComponent but in docs there is nothing about it. The worst thing is that I can apply force on mesh and body instance and I don’t see the difference. In one doc I found that Physics Bodies might be Body Instances, but then which one of these I should apply force to?

Its a Physics representation Container. FBodyInstance | Unreal Engine Documentation

There is no difference if you AddForce to the FBodyInstance or the UStaticMeshComponent (a Child of Primitive Component). As you can see from this Code https://i.imgur.com/fNLlF6G.png it will simply forward it to the Body Instance of the Bone you specified.

I knew it was the container but that piece of code is exactly what I needed. I guess it could be found in engine source code? Just so I avoid asking these quwstions and find the implementation on my own.
