ShowMapOnBack 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. UOffset Changes the U position of the map in UV coordinates on page 8161. The map moves in relation to its size. Default=0.0. 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. UScale Determines the number of times the map is tiled on page 8148 (repeated) along the U axis. Default=1.0. UWrap Turns tiling on or off in the U axis. Default=on. UMirror Mirrors on page 8148 the map left-to-right along the U axis. Default=off. VOffset Changes the V position of the map in UV coordinates. Default=0.0. VScale Determines the number of times the map is tiled (repeated) along the V axis. Default=1.0. VWrap Turns tiling on or off in the V axis. Default=on. VMirror Mirrors the map top-to-bottom along the V axis. Default=off. UAngle, VAngle, and WAngle Rotate the map about the U, V, or W axis (in degrees). Default=0.0. UVAxis Changes the mapping coordinate 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. Default=0 (UV). ■ 0 is for UV. ■ 1 is for VW. ■ 2 is for WU. Clip When on, UVs are clipped. When off, UVs are wrapped. Default=on. mental ray Shaders | 6009
