Alpha 20 Dev Diary in News & Announcements Posted September 16 17 hours ago, Roland said: I answered this somewhere else but it bears repeating. There are only wood frames (particle board) left in the game as far as frames that can be placed and picked up. They upgrade to wood for 10 wood which upgrades to cobblestone for 10 cobblestone which upgrades to Concrete for 10 Concrete Mix which upgrades to Steel for 10 Steel. Given the new unified system, does that mean that all the different types of block can now start as particle board? Previously things like bars, walkways, and stairs had to be made directly in wood rather than starting as frames, and therefore couldn't be placed experimentally and picked up again. Or do some shapes still skip the particle-board stage? Also, do the particle board versions of block have the same SI as wood, so we can build out of them and upgrade to wood without the heavier wood blocks collapsing if we do our upgrades in the wrong order?
