This video teaches you how to use the Minecraft mod ‘Wedge’ (we’ll assume you were able to get it running already) to control terrain generation. The first half-hour explains how octaves of noise work, and how they combine in 3D space. Then, we tweak Wedge trying to work toward a specific result for the next half-hour, until Minecraft crashes :) Settings are shown in the video, for Wedge users! The 1.8 terrain generation may use different controls, and I’ll try to follow up with a dedicated video for that when I have access to the feature.
