Hi, I am mostly a programmer, so this option doesn’t matter for me. We can ask our very experienced colleague <@467245702112739328>

It’s better to leave it disabled to not to kill the performance for complex meshes.

Ohh, okay then, thanks again for the tips, friends.

<@467245702112739328> Sergey, one question: before using the Pack Island function via the Pie Menu while holding Alt, do I need to select all the islands?
Sometimes I notice that it works without me selecting all the islands, and sometimes it only works after I select all the islands…

We would highly recommend to follow this tutorial and read the text comments

How do I configure it so that it works without me having to select all the islands first?
Imported from Discord
Tickmark must be unset

Also note that Pack Islands does not pack hidden islands. Especially if you are in UV No Sync Select mode and are working in UV Editor. Be sure that all mesh elements are selected
Imported from Discord
I don’t understand.

Pack Selected Islands option must be unset
Imported from Discord
Oh, right, but when I perform the procedure for the first time, it still opens this dialog box.
Is that normal?
Imported from Discord
If you are using Blender pack engine in ZenUV Pack, it may happen
Imported from Discord
Oh, I see, yes, I’m using that option. To prevent that from happening, I would have to use UVpackmaster, right?
Imported from Discord
UVP is the most powerful packing engine, it has its internal pack engine, so you will not see such dialog
Imported from Discord
Okay, then.
