I just realized I probably should've put this in the questions forum. Sorry guys, it's been a while.
Can't animals eat the moss that grows everywhere once you get to the caverns?
I don't get into the caverns anymore since it always kills my frame rate.
Won't work unfortunately. The game allows you to designate constructions attached to bridges, hatches, etc, but as soon as they've been built they immediately fall off. Not sure if it's a bug that you're allowed to designate them there, or a bug that they don't count as supported, but either way it's broken.
I just breach the caverns and then hollow out the entire soil layer. Free rainbow logs and pasture!
I'll have constructed walls on the floor below which will support the grates as shown in the above diagram. They're laid out in that pattern because it is the optimal one to reduce the number of walls needed. Notice how every grate tile is next to a section of wall.
I just wondered if this is a good idea or worth it. Apparently unnecessary?

Hmm, last time I tried this I constructed an outdoor wall with a catwalk above, and the dark area under the catwalk didn't appear to grow anything. Examination showed nothing but dirt. They're saying there was actually grass there, even if I didn't see it?
So I could build a tower, put a complete ceiling over it, flood the room with mud and grass would grow for animals? I thought from past experience that the area was only considered outdoor/lit, not that plant life would necessarily grow.
