I've googled around and tried all of these:
Setting landscape within Unity before exporting
Setting android:screenOrientation:"landscape"
on Android Manifest, in both the exported project and the Parent project (since the exported project will then be compiled as a library for yet another project)
Using setRequestedOrientation
at Runtime in the parent project
But it still seems to go Full Sensor. I just want it to lock at landscape, but nothing seems to work so far.
Thanks in advance.
