In Houdini, iNodes nodes live in Copernicus networks. Image and video models deliver their results there; 3D models, on the other hand, place their objects straight into your scene.
Find the nodes
In a Copernicus network, press Tab, then open iNodes. The nodes are sorted by category, then by model family.
Your scene as input
iNodes adds a special node to Copernicus to capture your scene: Layout Capture. It renders a camera with Houdini's viewport renderer, and its frames feed straight into an iNodes node. There's nothing to export.
- In your Copernicus network, press Tab, open iNodes, then choose Layout Capture, at the bottom of the list.
- In Scene, choose Objects or LOPs, then set the camera.
- Wire its output into an input of the iNodes node.
With Render on Generate, on by default, the capture is redone on every generation. On a video input, the iNodes node's Frame Start and Frame End decide which frames are rendered.
Where your results land
- Images and videos: they stay in Copernicus. Each result arrives as a File node, in your iNodes node's network.
- 3D models: they land straight in your 3D scene, like any object. iNodes files them in the iNodes_SOP object, under
/obj, and picks the loader for the format: glTF, OBJ, Alembic, USD or FBX.
