The Pack dialog contains controls for rearranging texture clusters procedurally in the Edit UVWs dialog.

Interface

(drop-down)
Sets the packing method:
  • Recursive Packing(Default option) Packs the clusters efficiently, but is slower than the Linear method.
  • Linear PackingUses a linear method to lay out the clusters. This method is fast but not very efficient, and tends to leave unused UV space.
Padding
The amount of space between clusters.

For best results, use a small value. In most cases, the default value works well.

Normalize Clusters
When on, scales the final layout to fit within the standard texture-coordinate space (0.0 to 1.0), indicated in the editor by a thick, dark-blue outline. When off, the final sizes of the clusters use object space, and can be larger than the editor mapping area. For best results, keep this setting on.
Rotate Clusters
Controls whether packing rotates clusters to minimize the size of their bounding box. For instance, the bounding box of a rectangle rotated 45 degrees occupies more area than one rotated 90 degrees.
NoteIn certain cases, Pack can rotate clusters by 90 degrees even if Rotate Clusters is off.
Fill Holes
When on, places smaller clusters in gaps among larger clusters to best take advantage of the available mapping space.
Rescale Clusters
When on, packing scales individual clusters so that texture element sizes are uniform. Alternatively, when groups with non-default Rescale Priority values are present, uses the specified scaling factors.
OK
Accepts the settings, closes the dialog, and performs the packing as specified.
Cancel
Undoes any changes and closes the dialog.
