■ Perform optimizations to speed later processing, such as merging fragments from the same surface that are in the same pixel. The result of initialization is a buffer. This is a compressed rendering that, like a G-Buffer on page 7991, contains the rendering plus additional information used by the second step, updating. During the initialize pass, progress is indicated by a row of pixels (white by default) that traverses the top edge of the ActiveShade window. Update Updates the ActiveShade window. Updating shading takes the buffer created by the first pass, initialization, and uses information in that buffer to change the color of pixels when you make changes to lights and materials in the scene. During the update pass, progress is indicated by a row of pixels (white by default) that descends the right edge of the ActiveShade window. To keep the ActiveShade window current, you need to choose Update Shading if you have previously turned off Automatic Shading Update. Select Object (viewports only) When on, you can select an object in the ActiveShade window by clicking. You can select only one object at a time. When an objects is selected in the ActiveShade window, the Initialize pass resamples textures for that object alone. This improves the window's rendering speed, and is useful when you are adjusting texture display. Toggle Toolbar (viewports only) Toggles display of the ActiveShade window toolbar in viewports. Keyboard shortcut: Spacebar NOTE The Keyboard Shortcut Override toggle on page 7858 must be on for the spacebar to toggle the ActiveShade toolbar. Options quadrant (lower left) These commands control how the ActiveShade window behaves. Act Only On Mouse Up When on, changes you make to light and material parameters (for example, the RGB or Multiplier spinners) update the ActiveShade window only after you release the mouse. When off, changes to these parameters are updated immediately, as you drag the mouse. Default=on. Turning off Act Only On Mouse Up can make the ActiveShade window more responsive to changes, but it can also slow performance. ActiveShade | 6113
