TerraForged is an ambitious new terrain generator mod for Minecraft (Java Edition) attempting to create more immersive, inspiring worlds to explore and build in. Featuring an overhaul of the vanilla generation system, custom terrain shapes, simulated erosion, better rivers, custom decorations, tonnes of configuration options, and more!
TerraForged's aim is to make your Minecraft world look & feel more coherent, expansive and interesting. It does this by combining a wide variety of hand-crafted terrain-type generators (many of which are inspired by real-life landforms) and then procedurally blending, eroding and smoothing together.
Unlike Vanilla - which generates the biomes first, and lets the biomes define how the terrain is shaped - TerraForged generates the terrain first and then decorates it with biomes that suit. Not only does this produce smoother and more natural transitions between contrasting terrains, but means that biomes are no longer fixed to a single terrain type, allowing for much more variation.
TerraForged makes use of an hydraulic-erosion algorithm to help improve the visual style of its terrain. This process traces the paths of thousands of water droplets down the slope of the terrain, simulating material erosion, carry, & deposition, and creates subtle lines and variations in the heightmap.
Data from this process is also used when decorating the terrain to expose the rock-face on highly eroded inclines, place gravel (scree) at the bottom of slopes, and to remove snow from locations where it wouldn't naturally settle.
