Suppose you want to "smelt" rocks without breaking ore reactions or "cheating" to acquire bars of random metals... would something like this work?
[MATGLOSS_STONE:SANDSTONE]
[NAME:sandstone][COLOR:6:7:0][TILE:'#']
[SEDIMENTARY][AQUIFER][SEDIMENTARY_OCEAN_SHALLOW]
[METAL_ORE:IRON:0]
Wouldn't that interfere with things if you wanted to smelt 'real' iron ore? Additionally, you can still smelt an alloy from a 0% ore. Just tried it. (Set random rock to 0% silver and 0% gold, forbade everything else, ordered electrum from ore.)
Dang, that sucks. I just started a new fortress with my 0% ore stones but I don't have a smelter up yet. It shouldn't interfere with just making iron though, because you have to specify the type of ore you want to smelt if you're not making an alloy. As long as I don't somehow forget that Hematite holds iron and Talc doesn't that aspect should be good (should have been good, rather, since if it doesn't also fix the reactions I'm not so keen on it.)
I was thinking more along the lines of just having it on the economic stones screen so you could say "don't use it!"
That way at least I won't make a billion andesite doors before I get around to dumping it.
You could just install mayday's graphics pack as it allows changing of any stones economic setting. Don't know why a graphics pack would do that but it does.
The Mayday graphics pack also incorporates a bunch of minor mods, IIRC. That's why people have so many problems using it in succession games - it makes their saves incompatible with vanilla DF. Maybe I'll download it and see what they've got going with the reactions.
