TouchDesigner imports geometry, animations and scenes using the FBX file format from Maya, 3DS Max, Cinema4D, Houdini and others

TouchDesigner currently uses the 2019.0 version of the FBX SDK.

FBX is a file format and set of libraries from Autodesk that is used to exchange models, animations and image/texture data between applications. TouchDesigner reads and writes FBX files and supports most of its features.

You can drag-drop a .fbx into a TouchDesigner network, or import it via the menu bar File -> Import File...

You can save SOP geometry to a .fbx file by right-clicking on any SOP and selecting 'Save Geometry...' from the menu.

The 3D data held in SOPs and passed for rendering by the Geometry COMP.
