Swamp Lighting Prefabs?

Alright then, I've asked about getting the swamp skybox settings before, and was told to use the prefabs. It worked back then.

And now, I need those again, but they don't show up in the Hammer prefab slot-thingy, top or bottom. Basically, no prefabs labeled swamp anywhere. I don't know where they went or why.

Anyone have them? :crying:

A million thanks!
