Fine-tune adaptive sampling in the Arnold renderer.
- [Instructor] If you want to shave…a little bit of time off of your Arnold production…renderings, you can enable Adaptive Sampling.…This option is in the Render Setup dialog,…in the Arnold Renderer tab, in a section labeled…Adaptive and Progressive.…When Adaptive Sampling is enabled,…Arnold analyzes the noise in the rendering…and devotes additional samples to the noisy areas.…The number of extra samples is set…with this parameter, AA Samples Max.…
Adaptive Sampling is only…appropriate for production rendering.…It is not appropriate for an active shade preview.…It would just slow down the interactive production rendering…without giving any benefit.…It's important to keep in mind that Adaptive Sampling…will only work if the AA Samples Max value…is greater than the Global Camera Anti-Aliasing value,…or the number of sample passes.…Also, Adaptive Sampling will only work…if the Camera Anti-Aliasing value is greater than one.…
At least one sample pass must be completed…so the adaptive algorithm will have something to analyze.…
