How get depth in ue4.26 arkit?

How i can get depth in ue 4.26 arkit?
I tried to do it through “Get AR texture” and choosing “Camera Depth” texture type, but I get just a white texture in the output

I am wondering this as well. There seems to be no support or docs on this either :confused:

It’s very sad, i find in code some info about scenedepth, but i can’'t use it. Maybe later it will documintation. But now it’s not work in iphone 12 with lidar.

It is not implemented.
You can cheer for it in the UE4 roadmap here:

Let Epic know, that this is important for some of us.
