The effect of UVW coordinates is demonstrated in the picture above. The object to the left uses Cubic
mapping. The texture slips when the object is deformed. The texture for the object to the right does
not slip since its original cubic mapping has been xed in place with UVW coordinates.
You may use multiple Texture tags on an object, with each Texture tag assigned to a different UVW
tag. To do this, add a new Texture tag to the object and set the desired projection type, such as at
mapping for a label. Next, choose Generate UVW coordinates. A new UVW geometry will be created
and the selected Texture tag will switch over to UVW mapping so that the texture is xed to the
object’s surface.
Each time Generate UVW Coordinates is used, a new UVW tag will appear in the object manager. A
Texture tag will use the rst UVW tag that appears anywhere to the right of it in the tag list. If no
UVW tag exists to the right of the Texture tag, then the Texture tag will use the rst UVW tag on the
tag list. In this way, different UVW tags can be assigned to different texture tags.
Assign UVW Coordinates
Selective UVW mapping is intended for you to optimize projection for a single
texture. If you want to use more than one texture, use the Texture tag’s
Selection parameter.
If the object has no UVW coordinates (i.e. no UVW tag), new coordinates are
created automatically.
This command enables you to texture an object with several different projection types using a single
UVW geometry and a single Texture tag.
To assign UVW coordinates
 Create a sphere and convert it into a polygon object with Make Editable.
 Create a new material with a texture, e.g. the Checkerboard shader, and
allocate it to the sphere.
 Change the projection type from UVW Mapping to e.g. Flat.
 Select the Polygons tool from the left toolbar and select several polygons.
 In the Object manager, choose Texture > Assign UVW Coordinates.
