Terragen, developed by Planetside Software, is a landscape-generation and rendering application for Microsoft Windows. A TGD file represents a Terragen project containing the settings and scene data needed to create a natural environment.
Depending on the project, the file can contain terrain, atmosphere, lighting, objects, and rendering settings. It is a working project file rather than a finished image or animation. TGD is a newer Terragen project format that replaced an earlier format.
Open the .tgd file in Terragen on Microsoft Windows. Use the application's Open command to load the project and continue editing or render it.
Files saved by a different Terragen version may require that version, or a compatible version, to open them correctly.
There is no general-purpose converter for Terragen world files. Open the project in Terragen and export the required result, such as a rendered image or animation, or export supported scene components in the formats provided by the application.
