Stereopixol explains how Arnold sampling values in Maya, and how to best manage samples.
Arnold renderer is both powerful, yet surprisingly easy to use. Still, there are some areas where users tend to stumble. One of those areas is the sampling section. Sampling will determine how clean a render (noise) is, and how long the render will take. Increasing sampling for the wrong rays can make render times increase significantly without a better image necessarily. That is why it is essential to understand Arnold sample values and how they work.
Stereopixol’s new tutorial covers sampling in Arnold, and how they work. The short tutorial shows how to calculate the sample values in Arnold using Maya. Samples are a subject that gets revisited often. Arvid Schneider covered how to work with the sampling section to get nice clean renders in Arnold, too.
