Dynamic Clouds Issue

So, I’m trying out the Clouds stuff, but I’ve run into a bit of a problem, and I haven’t been able to find an answer for it.

I’ve got Clouds in two places, but they only show up in one. Any ideas as to what might be preventing them from showing in the other place?

Where they don’t work:

Never mind. I didn’t recall that the parts in the game in the second screenshot are very, very high up. So high up that the clouds are actually below. I couldn’t tell because they currently vanish when you’re above them. My bad. Might help any weirdos like me out there who like building their castles in the sky.
