Octane Standalone Documentation

There are numerous nodes and methods for importing files into an existing Octane Standalone scene. The node or method chosen depends on the file type. To import geometry that is in FBX, Alembic, GLTF, or USD format, the Scene node should be used (figure 1). 

Figure 1: Importing using the Scene node

To import OCS or ORBX files into an existing Octane Standalone scene, the Import option found by right-clicking in the Node Graph Editor window should be used (figure 2). An OCS or ORBX file can also be added to an existing scene by dragging and dropping the file into the Node Graph Editor window.

All the various import nodes available from the Geometry category in the Node Graph Editor window are:

• Decal - Creates a Decal node used with the Decal texturing system.
• Gaussian Splat - Imports a .ply file for rendering gaussian splat-based point clouds. 
• Mesh - Imports OBJ files. 
• Mesh Volume & Mesh Volume SDF - Imports an OBJ file to be converted to a volume or SDF. 
• Reference - Imports an OCS or ORBX file as a reference, without necessarily loading them.
• Scene - Imports an Alembic, FBX, or USD file.
• Volume & Volume SDF -  Imports VDB files to be rendered as volumes or SDFs. 

Reloading Textures, Images, And Objects

Objects and texture may be reloaded or replaced once imported. At the top of any object or image node is the active path to that image or object. Click on the Load icon to the left of the path to choose a different file while keeping the rest of the scene intact. Click on the Reload icon to reload the object or image (Figure 3).

Exporting Scenes

In addition to saving scenes in .osc and .orbx formats, there is a node available in the Nodegraph Editor window under the Utility section of the Geometry category titled Geometry Exporter (figure 3). This node can be used to export the scene in either .fbx or .abc (Alembic) format.
