Realsense point cloud mesh export question

Hi y’all,
I am new to NOTCH but interested to see if i can create a pipeline between notch and unreal. Currently i am running a notch trial version and testing wizard Armin’s CMD run 1984. All works well, but… when trying to change the resolution in the depth camera node … it crashes. The realsense depth camera D435 works well nonetheless … any advise on this? Also, i would like to know, if possible, wether one can export this particular scene into unreal for instance? What would be the most convenient way you think? Is it possible to export the point cloud mesh generated in Notch with the realsense in alembic for further use in Unreal? How? Looking forward to your reply and thanks in advance!! Fred
