Developer Greg Coulthard has introduced UnrealCraft, a template for creating Voxel Worlds in Unreal Engine 5.5, featuring an Infinite World map for procedurally generated environments similar to Minecraft. Key features include a block building system, NPC support with NavMesh, item drop mechanics, biome diversity, liquid propagation, a rigged main character, a dynamic weather system, and game save functionality. Users need a powerful machine with an RTX-capable GPU and 16GB of RAM to utilize UnrealCraft, which is currently available for purchase. The project also includes maps for procedural worlds using various data sources.
