UV Mapper

UM Mapper is modifier, which may create standard UV coordinates. It may be applied manually to any object or at the same time it is a part of many standard geometry primitives

Properties of UV Mapper

Enabled	When enabled, UV maps will be created.
Type	Type of UV mapping. Available types are: Planar - Projects UV onto an object through a plane. Cylindrical - Wraps UV surface around an object. Spherical - Spherical mapping is based on a spherical shape wrapped around the object. Cubic - Cubical mapping is based on a box shape wrapped around the object. Parametric Surface Space - used by NURBS surfaces. Same as original UV space. Normalized Parametric Surface Space - used by NURBS surfaces. Original UV space is transformed to 0 - 1 range.
Axis	Defines main axis.
UV Channel	UV channel to generate
Center	Position or Center 'UV volume"
Rotation	Rotation of local coordinate system.
Size	Size of UV volume.
Fit to Content	Adjust position and size of UV volume, This btton is available if Auto Size is unchkeced.
Auto Size	If checked, position and size of UV volume will be computed automatically, so object will be fully inside of UV volume. If not checked, you are able to change size of aposition of UV volume.
Rotation Repeat	Number of rotations.

Planar Mapping

Planar mapping projects UVs onto a mesh through a plane. Therefore, it may be important to align the Planar map's position, orientation and scale to the surface.

	This image shows planar mapping with default settings. Main axis of projection is X, all angles are zero, position and size are automatically calculated.
	Same configuration, but Y rotation of mapping is changed to 45 degrees.

Cylindrical Mapping

Cylindrical mapping creates UVs for an object based on a cylindrical projection shape that gets wrapped around the object.

This image shows cylindrical mapping with default settings. Main axis of projection is X, all angles are zero, position and size are automatically calculated.

Big cylindrical surface is for illustration purposes only.
