Description

Better UV island packing algorithm that does not only consider bounding boxes of islands and packs more tightly (even if slower)

In terms of UV packing and UV unwrapping, it's common in other software to have a progressive heuristic solver. Something that you let run for a couple of seconds until you're satisfied with the result.

Is there a task for to improve the UV editor itself? Right now it still has remnamts of the image editor and it could be improved. I made a couple of proposals about it here and here

Do you mean Packmaster / Shotpacker addons?

Also, please, remember, that current packing behavior is good because it is fast, that is suitable for the most cases and especially nice for heavy meshes.
If to completely replace it with heuristics instead of adding it, it is possible to get the same problem as with the undo - low perfomance for every use case instead of when it's really needed.
