This dialog lets you choose which elements will be part of a baked material. Each element is an individual bitmap. When you display a baked texture in shaded viewports, some elements might not display.
Lists the elements available for rendering. See Baked Texture Elements for a description of the available elements. Click an element to select it. Use Ctrl+click to select (or deselect) additional elements individually. Use Shift+click to select a group of contiguous elements.
You can also double-click a single element name to add it to the list and close the dialog.
Click to add these elements to the list in the Objects To Bake rollout of the Render To Texture dialog.
