JoseConseco, I see, it turns out the UV geometry follows the different logic that the standard geometry. Anyway, we have a fix for your case and it is already available in the new version:
This release provides the new version of the add-on: professional.
The features currently available in the professional version:
Lock Overlapping: treat overlapping islands as a single island
Group By Material (Experimental): make sure islands sharing the same material are packed together. This feature is experimental: especially it can block when used together with ‘Pack To Others’ option in case no appropriate place is found for an island in the unit UV square. In such situation simply press ESC in order to cancel the process. For some UV layouts it is required to use the ‘Heuristic Search’ option in order to obtain a decent result from the grouped packing
Advanced Heuristic: use advanced methods during a heuristic search. With this option enabled add-on will examine a broader set of solutions when searching for an optimal one. As the number of solutions to check is much bigger it is recommended to use longer search times in this mode. Note that in many cases this method provides best results with ‘Rotation Step’ set to a large value (e.g. 90 degress) because such setting considerably increses the number of packing iterations which can be performed in a given time.
Why the professional version? Well, implementing advanced features for the add-on costs us a considerable amount of time. It wouldn’t make sense for us to work on this without a perspective of some additional refund. At the same time we are aware that there are a lot of people who simply don’t need such features. Forcing them to pay for something they don’t need is the last thing we would like to do. We think that introducing another add-on variant is a prefect solution to this problem
