[Bf-committers] [PATCH] archimap.py: pack all selected objects on *one* texture

[Campbell Barton]

Hi, Melchior, I had a  look at your patch. its for the archimap and its 
from  blender 2.41
This functionality is useful, since there is no precedent for this, 
(Blenders internal unwrapper does this 1 at a time) and since I have 
needed to to work the way its currently working Id prefer this be added 
as an option.

In any case, you can join the objects for unwrapping most of the time 
without much trouble.

- Will investigate  after 2.42 release.
if you want, see if you can add an option in the PupBlock for this and 
use the script from the CVS with Blender RC3.
thanks
Cam
