Object list List of objects Shows all selected objects. Because the dialog is modeless, you can change the selection while it's open, and the list updates dynamically. ■ Name column Lists the object's name. ■ Map Channel column Lists the object's current map channel setting. ■ Edge Padding column Lists the object's current edge padding setting. Selected Object Settings group Enable When on, the Channel and Padding controls are used for individual, all selected, and all prepared objects. When off, only selected object texture rendering uses these settings; "whole scene" rendering does not. Default=off. Padding The amount, in pixels, that edges are allowed to overlap in the flattened ("unwrapped") texture. Default=2 pixels. If the baked texture shows visible seams when you view it in shaded viewports or renderings, try increasing this value. Projection Mapping group This group contains the controls for generating a normal bump projection. See Creating and Using Normal Bump Maps on page 6384 Enabled When on, normal bump projection is enabled using a Projection modifier on page 1628. When off, the Projection modifier is not used. Default=off. To generate a normal map rather than a normal bump map, leave Enabled turned off. Modifier drop-down list When an object has been chosen, this list shows the Projection modifier. If multiple Projection modifiers have been assigned, their names are visible in the list as well. Pick Click to designate the high-resolution object from which the Projection modifier will derive normals. This opens the Add Targets dialog, which works like the Select From Scene dialog on page 228 to let let you select one or more objects on which to base the normal map. Options Click to open the Projection Options dialog on page 6416, which contains various normal bump projection settings. When Individual is chosen (at the bottom of the Objects To Bake rollout), the options affect the selected object; when All Selected or All Prepared is chosen, the options apply to all selected or prepared objects. 6404 | Chapter 20 Rendering
