Clip created by Terragen, a landscape and animation generation program; contains nodes, which are like pieces of your scene, saved separately from the entire scene that can be inserted easily into a project; includes functions like surface shaders and complex terrains that can be inserted into the scene.

To create a TGC file, right-click an aspect of the scene (objects, water, atmosphere, etc.), select Save Nodes as Clip File..., name your TGC file, choose your save location, and click Save. To insert a TGC file, select File → Insert Clip File..., navigate to your TGC file, and click Open. You can also right-click different aspects of the scene (cameras, lighting, objects, etc.), select Insert Clip File..., navigate to your TGC file, and click Open.
