Identify and control various render quality parameters

This tutorial shows how to identify and control the visual quality of parts of a rendering. It shows how to control reflection quality through the use of reflection samples and an adaptive sampling mechanism; how to control diffuse illumination quality; and how to control overall image quality through the use of several anti-aliasing controls.

Converting a simple file from 8.0 to 8.1, AA, Shadow and Blurry Reflections threshold values

This tutorial shows how to adjust 3 parameters when moving a file from version 8.0 to 8.1. These are the anti-aliasing threshold (Block Volume Subdivision Limit), Adaptive Surface Sampling, and Adaptive Shadow Sampling. The way version 8.1 uses these values has shifted and this tutorial shows how to adjust them when opening an 8.0 file in 8.1.
