Detect Stereo On

Hi there,
is there a way to detect if the stereo_on mode is enabled?
i tried to get this status by asking if Head Mounted Display is Enabled (is Head Mounted Display Enabled node) but that doesnt seem to kick in as soon the stereo_on mode is enabled… :frowning:

In the editor it works just fine if i start the VR-Preview, but i dont know what command this triggers so “is Head Mounted Display Enabled” is set to true instead of the normal build where it seems to be always on false…

maybe someone knows an answer to this ^^
