-Nomad: I know. I did cycle through to the day. I think I had the camera enter a shadow. And believe it or not, there's quite a bit of green space. I was on an island, and only had the dwarves to trade items. Melting wasn't really THAT big of an option, not without taking decades, or using exploits.
I actually got into the single digit FPS for most of it. Thats why the forgotten beast is made out of earthenware bricks. Other than rock, which wasn't thematic enough, I actually made the basin for the lava pit out of metals: Bronze, copper, gold, some silver, and the rest of the iron. (there were like 400 bars) But, the sluice i was going to use to fill it actually kept overflowing, dropping onto the windmills that power the 16 z level pump stack, which runs through the left side of the statue, and through the arm before it enters the keg. The pump section is made out of (i think) Dolomite, and iron, both magma safe materials. The keg is steel, i think. The arms are copper, the pick cherry wood, and bronze. YOu should see it in armok vision on the highest setting. It just kept clipping because its actually inside the caldera, sitting on the lava that I floored over.
Frankly, I love the way I made the support structure for the forgotten beast. 9 legs, but just before the main body, there's a hashtag shaped hallway system to make it look like it can actually support the weight.
A word of warning: It takes me several minutes to load the file. There's a LOT of objects.
