World Machine Features for Terrain Generation

Procedural Terrain Creation

Powerful Fractals

Terrains based on fractal noise are a mainstay of computer graphics... but all too often, they look too similar and are difficult to control.

World Machine's fractal generators allows you to create very unique terrain types and styles, ranging from realistic to incredibly stylized. Everything from typical noise-based terrains to extremely unique localspace fractals are possible!

Graph Based Interface

Procedural terrain is created not by sketching, but by connecting together devices that create or modify your terrain. This control over the process of terrain creation allows you to non-destructively modify your terrain, and change any rule at any time.

Blueprints, Macros, Groups

Sometimes graph based interfaces can get messy. Helping you is World Machine's powerful tools to aid understanding, including:

  • Grouping - Declutter, label, and organize your devices
  • Blueprints - easily add sets of devices you typically use together
  • Macros - extremely powerful devices that abstract an entire network of devices as a single device.

Guide and Sketch


Layouts allow you to control your procedural terrain by specifying what and where.

You can sketch out continents, indicate where mountains or valleys should reside, or place roads and rivers into the terrain.


World Machine's new river tool allows you to sketch a river and have it automatically create geologically accurate features such as meanders, ripple-pool sequences, and realistic valley walls.

Simulate Nature

Powerful Erosion Modelling

The natural world is not a perfect fractal. World Machine offers powerful natural effect tools to help create realistic terrain.

Flow based erosion creates gullies and carries away entire mountains given enough time, while

Thermal erosion breaks apart cliff faces and accumulates talus slopes beneath them.

From Sea to Snowy Peaks

There are several additional specialist natural effects available in World Machine as well.

Coastal Erosion quickly creates beaches and shapes the near-shore area. It also exports a set of handy masks to assist in texturing the various areas.

Snow simulates the accumulation of snowfall on the terrain. Snow accumulates and buries your terrain under soft features.


Advanced selection tools

Texture maps for terrains are traditionally created by using a combination of elevation and slope restrictions to govern what texture goes where.

World Machine gives you a richer set of masking tools to direct your textures with:

  • Basic Selectors : Elevation, Slope, Noises
  • Advanced : Surface Convexity, Relative heights, and Roughness
  • Natural filter outputs: Areas of erosion, talus deposition, and much more.

It's time to move beyond height and slope based texture distribution.

Texturing with Erosional Masks

World Machine supports exporting for both of the dominant texturing methods:

Weight maps

Weight maps (also known as splat-maps) are a set of one or more RGBA bitmaps whose channels act as normalized weights controlling the painting of textures at any given location in the world.

All of World Machine's selection and masking tools are directly applicable to creating weightmaps. In addition, a special splatmap converter device will make sure your weightmap channels are normalized and mixed to your preference.

Weightmap-based texturing


Megatexturing lets you create a texture bitmap that contains color and other information for every point in your world.

This method is particularily suited to the Professional Edition's tiled output function, which allows you to export the terrain and texture as a set of tiles, each containing part of the world.

Unique, high resolution texturing across the entire world.

Export your Creation

Tiled Terrain (Pro Edition only)

Export a large region as a set of tiles, enabling the creation of massive worlds far too large to create or store in memory as a single file.


Industry Standard Export Formats

Whether you're creating terrain for a game, feature film, or a visualization you can export your art assets from World Machine.

  • Export your terrain as a high bit-depth heightfield or a mesh OBJ
  • Export color and normalmaps in a variety of image formats

World Machine is compatible with game engines such as Unity, Unreal Engine, Amazon Lumberyard, Crysis Engine, and many others.

And of course, you can always export to your favorite 3D rendering package such as Maya, 3DSMax, etc.
