TerraGen is landscape-generation and visualization software from Planetside Software. A .tgworld file stores world data created and saved by the program, allowing the landscape to be reopened and edited in TerraGen.
The file belongs to TerraGen's native project data rather than being a general-purpose 3D interchange format. It is intended for use with TerraGen on Microsoft Windows; other software may not be able to interpret its contents.
Open the .tgworld file in TerraGen on Microsoft Windows. You can usually open it from TerraGen's file menu or by opening the file from Windows if the extension is associated with the program.
If TerraGen is not installed, the file may not open correctly in another application because it contains TerraGen-specific world data.
Open the .tgworld file in TerraGen and use the program's available export or rendering features to create a supported output file.
