Multiblock structure rework

Index · Next: Bose-Einstein Condensate multiblocks


A long-running push across GregTech and its addons: structures are checked once and cached, every multiblock reports exactly which hatches and casings are missing, and the shared StructureLib gained the pieces the rest of the pack builds on.

MBF and MVF Replacement with Hearth and Fridge

The Mega Blast Furnace and Mega Vacuum Freezer are replaced by the Exothermic Hearth and Endothermic Fridge at ZPM tier. These new machines increase in efficiency as they run-the Hearth gains parallels and the Fridge gains speed-and can optionally be accelerated with pyrotheum or cryotheum. A tier 2 Fridge unlocks in UMV as a more generous upgrade.
