Just a question; while I realize this topic is heavily talked about, I've got a somewhat odd question.

I realize that it is impossible to render currently existing above ground tiles subterranean.
However, I'm curious about how Dwarf Fortress determines whether or not a tile is above ground or subterranean.

The answer to this question helps answer my actual question, i.e. the weird one.
Is it possible to create subterranean tiles?

I believe that the solution, if it exists, involves the creation of multiple z-level towers of obsidian to generate tiles marked *Inside, Dark, Subterranean*.

Hi, I just recently started seriously modding DF, but have been tinkering back and forth with the Raws for several months now.
I decided to try and see if I could make a custom workshop, and sort of slapped a small test one together named desk.

However, as far as I can tell something strange is happening. I've successfully migrated in my desk, however the single reaction I've written out for it fails to show. I haven't the slightest clue why.
The raws I've written are:

building_desk.txt

reaction_desk.txt

Added to entity_default.txt

I've done my homework, flipped through Shaostoul's guide (both), done several world regens (upwards of 8 now I think; 5 of them on 31.12, 3 of them on 31.16), and wandered around scratching my head for a bit.
I also migrated in Shaostoul's cheat-training booths available on the wiki for comparison. Everything worked perfectly.
I'm sure we differ somewhere, but I haven't the slightest clue where. Any help would be greatly appreciated.
