If it didn’t, the entire place would oxidize and turn green before the player got there to see it – assuming that the player stays in range for the copper to receive random ticks.

Context: I’ve been learning a bit about LabPBR resource pack formats. I created the textures for the Chiseled Copper and Copper Grate blocks in the screenshot, the rest is from Hardtop Realaccurate 128x, can’t take any credit for those. But I think I did an OK job matching the material and effects. Going to work on the weathered variants now.
