This addon has saved me several hours per every week. I have not come across anything offering similar features, performance as this in any soft(except Houdini, but there are nuances). I cannot recommend it highly enough!
Minor feedback: With games there’s strict PPI dictated by client and are artists are forced to use whatever texture size fits the asset. Very often it’s wide 2:1 ratio (e.g 2048x1024). Currently it works well from First pack however if you press Pack several times, you might get severe distortions as I reported already. For example if your UV is already packed at 2:1 ratio, by modifying the model and then trying to Repack, you get severe distortions requiring to first pack at 1:1 ratio, then 2:1 every time. However it’s a minor nuisance.
Once again Thank you for this amazing tool!
