Got it! The quarry, anyway. It’s now known as a Miner, which covers a pretty small area (I think 9x9). I knew of it but didn’t notice the Advanced Miner, which starts at 33x33 and can be upgraded to cover a 65x65 area. That’s what I wanted to make. Expensive to make but it accomplishes a lot and looks fairly simple to operate.
Resonant Rise is super, by the way. Building and crafting is so so much smoother than anything I’ve experienced in Minecraft to date. The only thing is you’re kinda on your own to figure out what all the thousands of items actually are.
Still no idea on the texture pack or material/item piping thing.
