native final function bool FindSpot (Object.Vector BoxExtent, out Object.Vector SpotLocation);
Tries to position a box to avoid overlapping world geometry. If no overlap, the box is placed at SpotLocation, otherwise the position is adjusted. Return true if successful in finding a valid non-world geometry overlapping location.
It’s probably didn’t been implemented. If not body gonna give you better anwser, there set of trace functions in UWorld (usually you can get instance of it by ()) which let you recreate that behavior, there names begin with LineTrace* , Overlap* , Sweep*
