Choose Frame and RfM will automatically apply the settings needed to produce a denoisable image. The AOVs tab under Render Settings now contains a drop-down for each display driver from which you can select Frame or Cross-frame filtering. Using the denoising tool from RfM is fairly straightforward. This tool was originally created by Walt Disney Animation Studios and Disney Research for Big Hero 6 and as a result has already been tested and proven in feature film production. RenderMan ships with a new tool that offers an alternative approach to reducing noise in rendered images. To cut the amount of noise in a rendered image in half, it can commonly take four times the number of samples. Monte Carlo algorithms have diminishing returns on the number of samples.
96 samples per pixel, before and after denoising
