UV replicas go to primary’s coods but dont rescale.  
If its not possible to rescale replicas, how should i stack uv islands? Primary island become bigger than replica after repacking only solo and primaries islands.  
And also can i somehow lock scales of uv islands so they dont rescale when i pack it?

UPD: Solved it!

Still interested if i can lock the scales of islands so they dont rescale with packing

Sorry for the delay in responding. Currently, Zen UV does not have an option to disable island scaling when using the Blender Pack. However, you can disable this option directly in the Pack operator’s settings.

When using UV Pack Master, simply enable the “Fixed Scale” option
