There are a number of ways that you can use the denoiser workflow in Solaris.

Once you have setup your Solaris scene, you can do one of the following 2 setups 

Setup 1 - Fetch Node

1. In the OUT context, first, create a fetch node, and in the source field, locate your desired usdrender_rop 
2. Once done, drop down a denoise node and connect the fetch to the input.
3. Set mode type, output location, Asymmetry, Flow and debug options, and once ready to render, press the Denoise button.
   
   Houdini will then render the frame(s) set in the rendermanrendersettings node and once all the frames have been rendered, the denoise process will begin.

Setup 2 - usdrender node
