- Next, Create a RenderOutputDefine (Display Driver) node for each AOV file. This sets up the output file name and channel name be used for RiDisplay.
...
- To make this AOV render interactively you can add it to the interactiveOutputs selection in the RenderSettings node.
- Advanced: You can also add a statistics selection to the node. Typically used for diagnosis and tuning:
- "variance" – estimates the statistical variance of values contributing to the pixel in associated source channel.
- "mse" – like variance, but diminishes towards zero as the number of samples increases. Though somewhat noisy itself, this can provide an estimate for the amount of mean-squared-error versus a hypothetical ground-truth image.
- "even" – an image produced using only one half of the camera samples
- "odd" – an image produced using just the other half of the camera samples
EXR Metadata
You can add metadata to the EXR file to facilitate pipeline functions. The Foundry documents this here.
Essentially, on the Render Settings node:
