What is Terragen?
Terragen is a scenery generator, created with the goal of generating photorealistic landscape images and animations. It is already capable of near-photorealistic results for professional landscape visualisation, special effects, art and recreation. Terragen has been used in a variety of commercial applications including film, television and music videos, games and multimedia, books, magazines and print advertisements.
Terragen is a powerful solution for rendering and animating realistic natural environments. Create entire worlds from your imagination, or import real world terrain datasets and use Terragen to create the most realistic visualisations possible. You control the weather, landscape, rivers, lakes and oceans, suns, moons and stars. With Terragen you have complete control over the shader networks used for terrains, textures, micropolygon displacements, clouds and object distributions. You can reorganise the planetary shading pipeline to suit your goals. Place grass and trees wherever you want, as well as other objects in native TGO or OBJ format that you have modeled in third party software.
Comments and Reviews
Said about Terragen as an alternative
It's a bit more tricky setting up your landscapes via a schematic editor which works both for the height map and color texture maps. A lot more complicated but in the end it's very versatile.
