Blender 2.8 - Unwrapping VS Packing I am in UV Editor Mode, if I click unwrap (U) with a shell selected, it unwraps the shell correctly (following the seams) but at the same time it's packed in 0-1 space.

The tool is called "Unwrap" but seems it's doing "Unwrap and Pack". I can't figure out what I am doing wrong..

How can I unwrap the shell without packing it? Is it possible? 

I try to show with an example:

Shell i want to modify


Mark the seam
Select the shell 
Clicking Unwrap give me this: 

What i expect is something like this(just unwrap and no repack):  

Thank you
AFAIK the unwrap function always unwrap inside the 0-1 area no matter what.

If you want to unwrap again some parts of your UV without affecting the rest, you can pin what you want to keep before unwrapping.
Just select in the UV Editor, then click UVs → Pin or press P. Don't forget to unpin when you're finished with &#9095; AltP
