Working on my Gem mod, and ran into some problems I've yet to figure out with the placement of underground placeables. ------------------------------------- One of the tasks I have is to place crystal formations on the background wall. I know it can be done, as I've seen oil lanterns in such a location while delving myself. The object placed is "oillantern1", but I went through each of the underground biome files and I failed to locate any references to it, or any placement modes aside "floor" and "ceiling." I do not think that it was done as a micro dungeon, but if that is the case, then I'll just have to ignore this goal.
So it is a microdungeon then. I was hoping I was wrong in how frustrating that will be. It is a task I don't want to work on anymore for just handling the placement for all the biomes and tracking which ones I've done and should do. At this point, I just have crystals hugging the floor. Maybe I can work with it like that, but that will be something I do much further down then line then.
The underground [ rock layer ] should be seperate from the surface biome. As in it is the same underground layer for all sufrace biomes. Unless you know something I don't. And if you did I would be quite happy to know how to link rock layer to surface layer.
I don't think there is a way to force a certain layer to a surface biome. That would be neat, but the closest would be to create an underground dungeon that completely overwrites a layer. It might be possible to do that way with an offset or something to that regard or maybe dungeons so large that they overtake multiple layers. This is working with the understanding that you can generate a dungeon in the surface biome file and that dungeon can go below that biome by some sort of abuse of the system. I don't know much about how dungeons are generated sadly. It is not something I want to work on. All in all, there isn't a feasible way to link layers, as in having the layer above dictate which layers can spawn below. That would be a boon to some more interesting planets, if it could be done. I can only think of ways to completely replace one layer with microdungeons, and at that point, it would just be easier to change the underground biome file for all planets. Sorry I rambled. Fatigue is eating at my sensibilities.
