How to vary reflection smoothness according to incidence angle

In this material and rendering tutorial the ability to vary the degree of surface roughness according to view angle is explored. This is a powerful technique that simulates real world material properties which can be useful for architectural and product/package design.

Texturing a metal cooking pot, Part 1

This tutorial begins the process of setting up a complex material system for a cooking pot. It looks at creating a metallic material that uses a series of overlaying ‘modifier’ materials to create the final appearance. Material subsets, anisotropy, UV mapping and incidence reflectance are covered.

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.
