2 On the Coordinates rollout, set the U and V values to be between 0.0 and 100, or between -100 and 0.0. 3 Set the Offset Width and Height values to be between 0.0 and 100, or between -100 and 0.0. On the surface of the object, the map shifts in the directions you chose. UV offsets are especially useful when you have turned tiling off and want the bitmap to appear in a single location. To rotate the map: ■ On the Coordinates rollout, set the Angle U, V, and W spinners. Positive angles rotate the map in the clockwise direction; negative angles rotate it counterclockwise. The angle can be up to 360 degrees, which rotates the map completely and has no visible effect unless you are animating the map's rotation. You can also click Rotate to use the Rotate Mapping Coordinates dialog, which lets you change the rotation by dragging the mouse. To increase or decrease antialiasing: ■ On the map's Coordinates rollout, increase or decrease the Blur value. For diffuse maps and other maps besides bump maps, the Blur value is most effective in the 0.5-20 range. Lower values decrease antialiasing; higher values increase it. The Blur Offset parameter adjusts the image before antialiasing Blur is applied. If all you need is antialiasing, leave Blur Offset at its default of 0.0. To make a map image fuzzier: ■ On the map's Coordinate's rollout, increase the Blur Offset value. Blur Offset is a very strong parameter. The Blur Offset spinner has increments of 0.001 Values greater than 0.1 are likely to be too high. To make a map image sharper: ■ On the map's Coordinates rollout, decrease the Blur Offset value to a value below 0.0. The negative Blur Offset value sharpens the image. 5788 | Chapter 19 Material Editor, Materials, and Maps
