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 Packing Uses 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. Note: In 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.
