Notice that as sample counts get higher and higher, the difference in quality becomes more and more subtle. You can get an idea about this looking at the progression below, each slice is a lower Pixel Variance value left to right. When using RenderMan, you can increase the samples taken automatically by the renderer by decreasing the Pixel Variance parameter in small increments. The more powerful your computer (the more processor cores and more modern it is) the faster this will go. ![]() More samples will help the image improve, but this takes time. For a first iteration you may see something like the image below: Users are familiar with this effect when a render just starts up and then converges before their eyes. ![]() When rendering scenes using raytracing, the result of poor quality settings or insufficient time to converge shows noise. Your pixel filter should be set to "importance".
