Checked reel · 14 Oct 2026
Minecraft's 1.18 Caves & Cliffs update overhauled world generation using 3D noise math, exactly as explained in the clip. Mojang developer Henrik Kniberg broke down this exact system in his technical talks on procedural generation. Broad caverns come from low 3D noise values (cheese caves), while winding tunnel networks (spaghetti and noodle caves) are generated by intersecting two distinct 3D noise fields where both values sit near zero.
