Use the UVW XForm modifier to adjust tiling and offset in existing UVW coordinates. If you have an object with complex UVW coordinates already applied (such as a Loft object, or a parametric object with generated coordinates), you can apply this modifier to further adjust those coordinates.

For example, if you create a torus and turn on Generate Mapping Coordinates, the UVW coordinates work perfectly with the torus, but if you want to tile or move the coordinates, you would previously have needed to do it at the material/map level. Now you can apply a UVW XForm modifier to alter the built-in coordinates.

Interface

Mapping group

U Tile, V Tile, W Tile—Alter the tiling along any of the three coordinate axes.

Flip—Reverses the direction of the map along the specified axis.

U Offset, V Offset, W Offset—Move the map in the direction of the specified axis coordinate.

Channel group

Specifies whether to apply the transform to a mapping channel or a vertex color channel, and which channel to use. For more information on these channels, see UVW Map Modifier.

Map Channel—Specifies a UVW channel to use for the mapping, and use the spinner to its right to set the channel number.

Vertex Color Channel—Uses the vertex color channel for the mapping.
