Position personSegmentation (without depth) at a certain depth

I want to place my person segmentation behind a camera locked 3d plane (which I am using as an overlay).


Is this possible?


It works fine for personSegmentationWithDepth, but that seems to be taking up a lot of perf, which I don't really need as my scene is simple and can easily make use of the flat person segmentation.


Thanks for any ideas.
