With the new 'Mt Rainier' edition, your edits build fluidly in the background. This is the fastest World Machine yet.
You should sculpt only if you want to! Using a graph based approach, you can create terrain by connecting together components that create and modify your terrain.
Check out how easy it is to build a terrain at up to 8k resolution in realtime!
Graph-based approaches can sometimes get messy. World Machine helps you understand your graph:
The new 'Mt Rainier' version is built around undo/redo.
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!
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.
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.
With Snow you can simulate the accumulation of snowfall on the terrain. Snow accumulates and buries your terrain under soft features.
World Machine lets you add water that has real elevation, gradients, and flow
The river tool allows you to sketch a river course and automatically apply geological features such as meanders, ripple-pool sequences, and realistic valley walls.
The water flow vectormap is automatically calculated from hydrodynamic principles. All of this (geometry and flowmap) can be easily exported with your terrain.
You can work with water in ways far beyond simply sketching rivers:
Use the powerful Flow Restructure tool to change any terrain to make water flow correctly to sealevel. Valleys are raised, ridges cleaved, and small depressioned removed.
Create Water automatically adds river networks, and forms lakes where geologically appropriate. You can also flow water semi-automatically with an easy "click to flow" mechanism.
Coastal Erosion quickly creates beaches, shapes the near-shore area, and creates an ocean of water.
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:
It's time to move beyond height and slope based texture distribution.
You can create and export your terrain texturing in several ways, depending on your desired workflow:
Texture weightmaps (also known as splat-maps) are a set of one or more RGBA bitmaps whose channels act as weights controlling the distribute of materials at any given location in the world.
All of the various selectors and natural erosion masks can be combined as you see fit to create your weightmaps. The Texture weightmap tool will make sure your weightmap channels are normalized and coverage adjusted to your preference.
Avoid the repetition of tiled textures and create a unique high resolution material that provides color at every point in your world (sometimes called Virtual Texturing or Megatexturing).
World Machine's high-resolution output abilties lets you specify a unique texture down to the sub-meter level. This works particularily well with tiled terrain in the Professional Edition.
When you're done editing in World Machine, just hit the export button, and all of your assets are created at the resolution you request.
The terrain geometry can be output as a heightfield or mesh for your target application of choice.
A wide variety of bitmap formats are supported to export your mask and material data.
If you're creating a massive open world, a single asset to describe the region is no longer suitable.
With the Professional Edition and above, you can export a set of tiles covering your region. Each tile is built seperately, allowing for both extreme detail and a nearly unbounded world size.
Whether you're creating terrain for a game, feature film, or a visualization you can export your art assets from World Machine.
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 Blender, Maya or Cinema4D.
