You can add a RenderMan RIS_ IPR ROP from the RenderMan Shelf or from the /out pane.
Using RenderMan Shelf
We can use the ROP tool in the RenderMan Shelf to create a ROP that automatically adds an integrator VOP to your RIS Network.
Using out pane
Add RenderMAN
...
IPR ROP
Add Integrator
...
Simply drag the path of your integrator VOP path to the Integrator in RenderMan RIS ROP. If you skip this step, by default, it will use the PxrPathTracer integrator with its default parameters.
