Fixed occluder issues in Zenith and Core, more controllers recognized at once. — DreamWatcher Steam update #1050442

Fixed visual bugs and a quality of life issue: There was a room in the Zenith where the walls would turn transparent when viewed from a certain angle and three doors in the Core where the next room was invisible until crossing the threshold, those issues have been fixed. Players with multiple controllers connected should now be able to use any of the first 8 they have without having to disconnect it and reconnecting it in the first port.
