OctaneRender® can import many different geometry types by clicking on the Geometry menu in the Node Graph Editor window (Figure 1). Typical geometry types such as FBX, OBJ, USD, Alembic, as well as Gaussian Splat and volume formats are supported. These various file format types are covered in this section.

If a scene contains multiple objects or animations, the FBX, USD, or Alembic file (ABC) format should be used. These formats can be imported using the Scene node. After importing the scene, connect it to the Render Target. You can combine multiple objects by using a Group node. If you need to reposition the object, connect a Placement node between the object and the render target. 


When an imported scene contains more than one object, the individual objects can be accessed by double-clicking on the import node. 

NOTE

This will only work if a text (.txt) file has been placed in the install location of Octane Standalone. The text file needs to be named as octane_log_flags.txt. And, the file needs to contain the following log flag: makeAllInspectable.


To determine how Octane renders meshes imported into a scene, you can adjust the settings in the Geometry Import tab of the Preferences window. These settings can also be accessed by clicking on the Wrench icon in the Node Inspector when the mesh node is selected (Figure 2).
