I found the 3rd cavern a while back.  However, I wasn't able to locate any nether-cap at all .  Is there still a chance for nether-cap to grow in empty soil tiles elsewhere or does this require at least 1 nether-cap tree down below?

I'm reasonably confident that if you don't have a plant type in the caverns already it won't appear anywhere else.

[VerdantSF]

I was afraid of that.  Required spores and all that.  Drat.  I wonder why nether-cap never grew in that cavern.

It seems a bit random. When fiddling with world gen I noticed that if I created the exact same same world but with different history parameters, in some results the exact same embark would have slightly different underground trees, sometimes all, sometimes missing one or two. Nothing else seemed different (except the random stuff like underground civs and animals present).

Yeah, it's my understanding that basically, if you don't see it growing already in the caverns, you won't see it pop up in your tree farm/soil areas. That's a real bummer, because I happen to agree that Nether-cap is the coolest (get it!? harhar!) wood to have around. The always cold property of it is a really neat idea. Love to see it used as an ingredient in fancy dwarven artifacts and such

I want to make dragon turrets, but nether-cap buildings are the only ones that can withstand dragonfire .

[XXSockXX]

If it isn't a new fort and you can't start over, there is nothing you can do. Except maybe check the entire cavern very carefully in case you overlooked something. (It may be rare but possible IIRC to have different cavern biomes on the same cavern level.)

If you want to start over, just re-gen the world, but change history a bit or let in run slightly shorter or longer, embark at your spot and check with "reveal" what trees there are.

If you don't object to DFHackery, you could potentially add nether-caps to the 3rd cavern layer to make them start growing. Exact details on how to do it can probably be found elsewhere.

What about dolomite?

[wierd]

Dragon fire is different from magma. Magma-safe != dragonproof.

Nethercap avoids the issue completely by being a constant, fixed temperature.

Do you have any artifact doors or floodgates lying around? You could use those in lieu of bridges, which is what I assume you wanted the nether-cap for. You'll also need artifact mechanisms, but you'd need those with nether-cap bridges, anyway.

Oh, I totally forgot about those!  Thanks!

I'm not entire sure that even DFHack would work. You'd be able to place those trees, but the spores that make new trees are not something you have control over. It is very unfortunate, I agree though, because I often have this problem with worldgen. Nether-Cap seems to have a lower priority in my experience, and often all I get is Bloodthorn. (which admittedly would be useful if Batista were more useful)

Actually, creating the spores is exactly what I was proposing, and DFHack is absolutely capable of doing that. Here's a Lua script which does it:

Code: [Select]

feat = df.global.world.cur_savegame.map_features[2]
num = #feat.feature.population
feat.feature.population:insert('#', { new = df.world_population, type = df.world_population_type.Tree, plant = dfhack.matinfo.find('PLANT:NETHER_CAP').index });
for i,j in pairs(df.global.world.populations) do if (j.population.cave_id == feat.layer and j.population.population_idx == num - 1) then df.global.world.populations:insert('#', { new = df.local_population, type = df.world_population_type.Tree, plant = dfhack.matinfo.find('PLANT:NETHER_CAP').index, population = {region_x = j.population.region_x, region_y = j.population.region_y, population_idx = num, cave_id = feat.layer, depth = feat.start_depth, unk_28 = -1 } } ) end end

Note that this assumes that the 3rd map feature in your embark is the 3rd cavern layer (e.g. if you type "feature list", then features 0-2 should all be "the cave" with type "subterranean_from_layer").

Also, artifact doors/floodgates are NOT immune to dragonfire - while artifacts cannot burn, they can definitely melt...

Thanks for the script!
