bounding box issue

[Seeseallllll]

I want to use NDDS to get bounding box of human mesh.

I added component NVCapturableActorTag to the body actor.
However, no matter the body mesh downloaded from the Internet or some third-person character body mesh in UE, all bounding box of captured data are [0,0],[0,0]. Other objects don't have this problem. Why is that?

(Data is captured in the third-person component, but it is the camera's bounding box.)
