This rendering and material tutorial shows how to get more detailed glass by working with two render parameters: Reflection Bounces and Surface Shading Threshold. It discusses the concept of incidence 0 and incidence 90 and how that relates to this threshold function, in turn affecting glass type materials.
START FILE HERE is the Photoshop layered file shown in the video.
Note: The 3D start file contains both a 7.5 and 8.1 version depending on which application you are using. The 8.1 version will look a bit different than what is shown in the video files since they were recorded in 7.5. In addition, 8.1 will render this file quite a bit faster than 7.5, so the times shown in the Photoshop example file are for 7.5.
