I bought the pro edition here a couple weeks back, and I have to say, it’s a brilliant add-on. It’s quick, easy to use, produces excellent results, and saves me from the freakishly boring exercise in tedium that is UV packing – Renzatic (source)

The packer is available in two editions: Standard (with limited features) and Professional (fully featured). The differences between editions are depicted in a table:
|efficient UV packing algorithm|
|UV islands area measurement|
|overlapping UV islands detection|
|heuristic search algorithm|
|packing for a non-square texture|
|add new UV islands into existing packing|
|select/align UV islands of a similar shape|
|accurate pixel margin calculation|
|packing to a custom UV area rectangle|
|overlapping UV islands lock|
|grouping UV islands|
|advanced heuristic algorithm|
|UV map validation|
|defining rotation step on a per UV island basis|
|packing on GPU*|
|heuristic search on all devices simultaneously (CPU and all GPUs)*|
* – available on Windows and Linux
The demo edition is available for free. It has all capabilities of the professional edition, but the packing result is rendered in a separate window – it is NOT applied to the UV map. You can download the demo from the Downloads page.
