Thanks for the feedback, I will add metal item melting and leggings in the next Genesis release .
More thoughts.
I experimented with the tweak to Wood to allow for multiple types, and honestly found it kinda of.. hokey feeling. Unless one's really worried about material density in their -crossbow/bow-, I no longer think it really matters. That, or unless wooden melee weapons are being added.
I also experimented with metal item building a bit and have more thoughts. You might want to consider requiring people to make some large stone construction (that's too heavy for most strengths to deal with carrying at a movespeed higher than 200), so as to make it less of a quick-thing to use. Perhaps requiring knapping up things into brickish types, gathering something to put it together -and- wood for burning in it. Will it stop people from abusing? Heck no, but it'll slow them down! ^_^
Another thought would be not to allow an 'any metal' type, but instead allow rendering down of only copper and bronze, maybe iron items. I don't know if that'd make it easier to make a reaction for than 'all metal', but it'd again make it harder to abuse things as badly. The many items to make one bar, then many bars to make an item will help, but the goal in my mind was to make it so one couldn't take a handful of gold coins to make a massive maul, or likewise a few steel ones to make a breastplate. Again, not a perfect fix, but still at least a -nod- at a semblance of balance. The end result however means if you're having fits of bad luck finding anything anything -besides- a bunch of cave critters and small gauntlets of iron, you could do something about replacing your wood, bone, and leather gear. And especially helpful if you like playing with races that are above/below standard sizes, further increasing the hassle of finding anything good.
Unfortunately, my lack of skill hasn't helped me figure out how to make a metal based melt-down reaction, so I've had to operate my tests on 'good faith', so I don't just use metal for the first bit of making something, then a whole lot of troll-brains. ^_^
