Render quadrant (upper right) These are general-purpose commands. Show Last Rendering Displays the last rendering in a Rendered Frame Window on page 6073. Not available if no rendering has been made during this session. Render Setup Displays the Render Setup dialog on page 6067. When you use the ActiveShade quad menu, Render Setup is set to render the ActiveShade window initially. Render Last Repeats the last render, using the last viewport from which you rendered. Material/Map Browser Opens a modeless Material/Map Browser on page 5357 dialog. Material Editor opens the Material Editor on page 5284. Tools quadrant (lower right) These are the commands that perform ActiveShade operations. Draw Region When on, lets you draw a rectangular region of the ActiveShade window. While it is active, only the region is updated by interactive reshading. This can save time, and also help you concentrate on just a portion of the image to be rendered. Default=off. To turn off Draw Region, click outside the rectangular region. The entire ActiveShade window is updatable again. Initialize Initializes the ActiveShade window. To keep the ActiveShade window current, you need to choose Initialize after transforming, modifying, or otherwise changing geometry. If you have turned off Automatic Reinitialization, you also need to choose Initialize after you update a mapped material. Rendering can be slow. The initialize pass is meant to take care of the most time-consuming portions of rendering, to allow the update pass to take place as quickly as possible. Initialization includes the following steps: ■ Evaluate the scene geometry into meshes. ■ Apply space warps. ■ Do transformations and clipping. ■ Evaluate textures and shade materials. 6112 | Chapter 20 Rendering
