You can make a chunk as a level, then have one actor that acts as a chunk. That actor would have 4 child actors that you’ll connect to the chunks next to it. Then have either instanced meshes or static meshes spawn at random z cords in a grid (you can watch the UE4 livestream about it). But my advice is don’t do Minecraft as your first project. My first project that I’m working on is a parcore shooter (think Karlson but different graphics, no slow mo, and some other differences), and oh my god it’s difficult. I’ve spent 25 hours just working on aiming which other people do in 5 minutes (quite literally). You should start with something simpler, because once you get into it I guarantee you’ll want to keep going no matter how hard it is, and itll just be bad.Trust.
