Until now, those paths seem to have been unnecessary shortcuts or dinky chests. But now I think I need to get past one to progress on the main story... Am I missing another path to check out, or am I missing some way to get past these?

It's called "pixel-hunting", and I really HATE games that really on that approach for their "puzzles". You have to essentially sweep the cursor back and forth, back and forth, like a beachcomber's metal detector, a gazillion times on EVERY screen, just to be sure you didn't miss anything. Andin first-person 360-environment, that's a helluva lot of sweeping. As opposed to playing the game. Work, work, work, mindless work.
