purposes, planar mapping doesn't project through to the back of the object unless you turn on Show Map On Back. ■ Spherical Environment, Cylindrical Environment, Shrink-wrap Environment Project the map into the scene as though it were mapped to an invisible object in the background. See Environment Map on page 7964. ■ Screen Projects as a flat backdrop in the scene. Show Map on Back When on, planar mapping (Planar from Object XYZ, or with the UVW Map modifier) projects through to render on the back of the object. When off, planar mapping doesn't render on the object's back. Default=on. This toggle is available only when Tiling is off in both dimensions. Its effect is visible only when you render the scene. NOTE In viewports, planar mapping always projects to the back of the object, whether Show Map On Back is turned on or not. To override this, turn off Tiling. Use Real-World Scale When turned on, applies the map to objects using the real-world Width and Height values instead of UV values. Default=on. When Real-World Scale is on, the texture placement is relative to the corner of the texture map so alignment with architectural objects likes walls is more efficient. When off, the texture placement is relative to the center of the texture map. Offset Changes the position of the map in UV coordinates on page 8161. The map moves in relation to its size. For example, if you want to shift the map its full width to the left, and half its width downward from its original position, you enter -1 in the U Offset field and 0.5 in the V offset field. UV/VW/WU Changes the mapping coordinate on page 8034 system used for the map. The default UV coordinates project the map onto the surface like a slide projector. The VW and WU coordinates rotate the map so that it is perpendicular to the surface. Tiling Determines the number of times the map is tiled on page 8148 (repeated) along each axis. Mirror Mirrors on page 8148 the map left-to-right (U axis) and/or top-to-bottom (V axis). Tile Turns tiling on or off in the U or V axis. 5790 | Chapter 19 Material Editor, Materials, and Maps
