Material ID Displays the Effects channel used by materials assigned to objects in the scene. The Effects channel is a material property set in the Material Editor and used during Video Post compositing. Each Effects Channel ID is displayed using a different random color. Object ID Displays the G-Buffer on page 7991 Object Channel ID assigned to objects using the Object Properties dialog. The G-Buffer ID is used during Video Post compositing. Each G-Buffer ID is displayed using a different random color. UV Coordinates Displays the range of UV mapping coordinates as a color gradient. This channel shows where mapping seams might occur. NOTE UV Coordinates will not be displayed on objects that have the UVW Map Modifier applied unless a map has been applied that uses the coordinates. Normal Displays the orientation of normal vectors as a grayscale gradient. Light gray surfaces have normals pointing toward the view. Dark gray surfaces have normals pointing away from the view. Non-Clamped Color Displays areas in the image where colors exceeded the valid color range and were corrected. The areas appear as bright saturated colors usually around specular highlights. Coverage This saves the coverage of the surface fragment from which other G-buffer values (Z Depth, Normal, and so on) are obtained. Z-Coverage values range from 0 to 255. To see Z Coverage, render to an RLA file after first checking Z Coverage in the Setup subdialog, then choose Z-Coverage in the Rendered Frame Window's Viewing Channel drop-down list. The Z-Coverage feature is provided primarily for developers, and should aid in the antialiasing of Z-buffers. Descriptive Information group This information is saved with the file.
