Remarks
Trace a ray against the world using a specific channel and return overlapping hits and then first blocking hit Results are sorted, so a blocking hit (if found) will be the last element of the array Only the single closest blocking result will be generated, no tests will be done after that TRUE if OutHits contains any blocking hit entries
Parameters
