Hi, I am developing a realistic sonar sensor that requires the pointcloud data after one times of ray bounce,

I am very satisfied with replicator’s performance with ‘pointcloud’ annotator; however,
replicator’s pointcloud annotator can only give a direct ray query result, no bouncing.

so far I am testing RTX radar with parameter

“TraceTreeDepth”: how many times the rays are reflected

I am wondering if there are a more straightforward approach, by using RTX ray cast, to acheive this?

Any suggestions are appreciated.
