Spherical Mapping

Summary

Description

Determines the orientation of the sphere's major axis (it's top and bottom.)

These settings allow repositioning of the model with respect to the mapping sphere.  This is sometimes necessary when mapping models that aren't symmetrical.  For example, suppose you want to spherically map a model that consists of a quarter sphere.  By default, the mapping sphere will be centered on the model's geometry and would give undesired results in this case.  To correct this, you can enter an offset here to adjust the center of the mapping sphere to get the desired results.

Changes the position of the seam of the mapping sphere.  It is specified in degrees, and is clockwise about the negative axis (see "Axes Alignment" above.)

Selecting this option will cause a border of blank space to be placed around the entire mapping area.  It's a good idea to leave this option checked since each 3D rendering program can interpret UV coordinates slightly differently and it's a good idea to paint over the edges of a map by a few pixels.  This isn't possible without gaps in the map.

Checking "Scale Result" will cause the resulting map to be scaled based on the "Pixels Per Unit" setting under Preferences.

Unchecking this will cause all facets that share a vertex at the top or bottom of the cylinder to also share one UV coordinate as well.  This is usually undesirable and is not recommended.
