I've got a unity project that uses the convert-to-entity process to create a subscene for a group of mesh objects. In this screenshot it is the map/landscape assets Note that these are not terrain, but in this sample are just a demo level out of a syntystudios asset pack. If I hit PLAY in the editor, my character can run around on the map without issue. If I build this app to an oculus quest (being sure to include the subscene in the list of scenes I build and run) The landscape disappears in-game. I've got the hybrid renderer package installed, but is there something else that I am missing?
