In this video I’m checking out Building System Supreme by Silver Spur Studios (it was gifted to me for free), and yeah… it’s actually kind of insane. The big headline is it’s 100% multiplayer replicated, which is the part most of you care about if you’re building anything survival/sim/Fortnite-ish in UE5. I jump into their demo project, hit B to enter build mode, and immediately you can see they’ve got a polished UI flow, a library system for buildables, and a ton of “sim game” features baked in—foliage/land tools, visual themes, resource pickup systems, animated NPCs, and a lot of pieces to build with. I spend way too long “lawn mowing” because the land tools are genuinely sick: you can destroy foliage, re-plant different types, and even cultivate stuff like boulders with adjustable speed/size (Ctrl + mouse wheel for speed, Shift + mouse wheel for size). Then I swap over to building: snapping, scaling, sloping, and rotating pieces is fast once you learn the keybinds (and there are a lot of them). I also mess with animated buildables/NPCs and even trigger actions that let you run your own Blueprint event code. My takeaway: if you want a networked building + sim foundation without reinventing the wheel, this plugin is a solid “ready to make a game” starting point.
