when you want to transfert lots of objects
is there a way to select all or may be how to select whole layer or scene
to speed up things
now it seems that when you append an object it does not use existing materials it creates a new material
is there a way that i would use the equivalent material in the existing file where it is append?
EX: if i already have a material called black1
and whn i happen an object with the same name it should reuse the existing one in the fil
not create another new material
this take a lot of space - datablock
Thanks
