I'm building my artificial biomes in Terraria so I can farm certain things and have enemies spawn. The question is how big do the biomes need to be?
So far I've built a crimson, underground jungle, surface jungle and a desert but none of them are spawning monsters. I've read the Guide on Artificial biomes on Terraria wiki and many other forms but I have not found my answer. Can someone please give me detailed information?
I have enough blocks to where the background and music changes for each biome and yet still no monsters.
