7 Best Free Terrain Generator Software For Windows

Here is a list of Best Free Terrain Generator Software For Windows. These freeware are used to generate terrains and heightmaps using a variety of drawing tools and customization features. You first have to setup parameters like map size, color, displacement, noise, warping, etc. You can then define various environmental components and setup related parameters to create terrain. These components include water (water object, water level, center, max radius,), atmosphere (haze density, bluesky density, height control, sun location, sun minimum ambience, etc.), lighting (display type, intensity, altitude, latitude, slope, facing, blending), etc.

In some of these, you can also import heightmaps, surfaces, textures, etc. in BMP, JPEG, PNG, etc. formats. You can then modify the imported data file with provided tools. These provide various drawing tools which can be used to shape up terrain, such as raise surface, lower surface, fill, cliffs, bulldozer, leveler, smooth, noise, etc. Some of these terrain creator software also provide options to select lightmap style, texture filter, display options, etc. Most of these are 3D terrain generator as these provide 3D view to design and navigate through the created terrain.

The export formats in these terrain generators vary from one software to other. Some of the common formats include BMP, JPEG, DXF, PNG, PCX, etc.

My Favorite Terrain Generator:

Terragen is one of my favorite 3D terrain generator software for Windows. It is a feature rich software which creates a realistic image of a terrain with specified parameters. L3DT is also a good heightmap generator as it lets you create various types of terrain maps including Perlin heightmap, fractal heightmap, etc.

L3DT



L3DT is an acronym for Large 3D Terrain. It is a free terrain creator software for Windows. This free version contains few feature limitations as compared to its full version, like batch feature is unavailable, map size is limited to 2048 × 2048 pixels, etc. You can see full comparison list here.

You can design a few types of maps including designable map, Perlin heightmap, fractal heightmap, and blank heightmap. These heightmaps differ on the basis of algorithms and configurations. You can also import heightfield, design map, texture map, color map, etc. to the current project and perform different calculations and operations. It also lets you add different map layers to your project with layer type (heightfield, water map, attribute map, etc.), layer size, etc.

As you start a new project, it lets you choose the desired project type and specify the heightmap size (width, height, horizontal scale, split map into tiles, etc.). In addition, you need to setup design parameters like average altitude, altitude range, lakes, erosion, default climate, etc. Based on the chosen project, you need to set up parameters for the algorithm. For example, for Perlin heightmap, you need to specify feature scale, octaves, persistence, altitude range, etc. Next, you have to select components for Calculation Queue including Heightfield, Water map, Attributes map, Light map, Texture map, and Terrain model. Also, you get to configure options for water flooding (water level, water type, etc.), water table modeling (maximum depth, rise parameter, fall parameter, etc. ), light mapping (sun position, colors and intensity), and light/water effects. You can save any of these configurations as presets and use them later. From Resources menu, you can manage climate, materials, masks, and overlays properties.

The display options you get include display effects like draw mosaic tiles/scale bar/map titles, show water table salinity, show gradient coloring, etc., set view area, image drape, etc.

From Operations menu, you can view and manage Calculation Wizard and other operations, such as Design map, Heightfield, Water map, Attributes map, Terrain normals, Light map, Alpha map, etc. Also, you can edit heightfield in 3D using tools like raise brush, lower brush, raise to, lower to, cliffs, bulldozer, leveler, smooth, Perlin noise, etc.

Some other useful tools present in this heightmap generator software are Design map brush (altitude, peak rough, terraces, erosion, climate, etc.), Water flood tool, Ruler (to measure distance between two coordinates), etc.

You can save the project as an L3DT project file only. But, it lets you export chosen map layer in multiple file format, such Terragen, Wavefront, DirectX, 3D Studio, GLScene, RAW, BMP, PNG, PCX, PGM, etc. You can also edit format specific options. In addition, you can set up format preferences using dedicated option from File menu.

L3DT is a featured heightmap generator software for Windows. It provides some additional utilities too, like RAM chart, Throttle CPU, Event Log, Georeferencing, etc.

  3. Paint: To modify color and texture of the map.
  4. Detail: It lets you set detail textures for the map by setting up parameters like slope, radius, strength, softness, noise, scale, etc.
  5. Lighting: Here, you can generate entire lightmap and change sun’s direction and shadow. Other parameters to modify include Ambient, Blur, Pitch, etc.
  6. Water: You can enable water to display it on the map while adjusting parameters like height, scale, opacity, speed, refraction, distortion, and water material.

It provides two methods to render the custom terrain map which are Perlin Noise and Detail Height. The final terrain map can be exported as heightmap image or terrain texture (PNG), you can simply save it as object (.obj).

EarthSculptor is a great software to create terrain in real time. It produces high quality terrain maps.
