Yeah, that sounds smart. That way a reasonably powerful furnace could be built at any y-level, but you couldn't build a "high-powered" version without large amounts of resources.I like the idea. I may toy around with that. It would have to be balanced using both methods, the y level determines how effective it is while the distance multiplies the effect. Could work. Keep watching and see what comes out
I'll be keeping an eye out, for sure.
