Hi Alphatierchen!
In the BP node “Connect With Knuckles Source”, there are two tick boxes:
“LeftWithController”
“RightWithController”
If you enable either one or both of them, you’ll get the WithMotionController SkeletalRange data streaming in.
In C++, it is controlled by the following public vars in KnucklesLiveLinkSource
bRangeWithControllerL
bRangeWithControllerR
Hope that helps!
