click on "Open body sensor #1" is gives "Cannot open depth sensor #1 astra_imagestream_request_modes_invalid operation" error.
If you have only one sensor, connected to PC, you have to use "Open Sensor #0".
if i select with body trachking checkbox and click on "Open body sensor #0" button then it open black box with no data. please help me understand this.
Hm. If you don't check "With body tracking", can you see depth map?
Also, you can run application under debugger and check content of "Output Window". May be something interesting is reported by Astra SDK there.
UPDATE: OMG! I forgot to set copying to output directory for
OrbbecBodyTracking.dll in project settings. Sorry for that. Please, use the latest version from github (I'v just fixed this issue).
