There are five types of Render Kernels in OctaneRender®: Direct Lighting, Info Channels, PMC, Photon Tracing, and Path Tracing. The kernels are accessible by clicking on the Render Target button in the Node Inspector and choosing the kernel type from the Kernel parameter under the Render Settings rollout (figure 1).

You can also place a Kernel node in the Nodegraph Editor and connected to the Kernel pin on a Render Target node (figure 2).

The Kernel node can be accessed by right-clicking in the Nodegraph Editor and choosing the Kernels category.There is a Kernel Switch node under the Utility section. This can be used to switch between different kernel types assigned to one Render Target node.
