[Bf-python] Ask for: link/append/import returns object(s) instance(s)

Wed May 25 09:14:40 CEST 2011

Thanks,

would it be possible that the bpy.ops.wm.collada_import method could select
all imported objects ?
for instance if I have a car plus 4 wheels in the file "atrv257.dae", and I
do:
#
bpy.ops.wm.collada_import(filepath="/home/pierrick/atrv257.dae")
print(bpy.context.selected_objects)
#
the output is only:
[bpy.data.objects["Wheel_1"]]

and I would expect to have something like:
bpy.ops.wm.link_append(directory="/home/pierrick/atrv.blend/Object/",
link=False, files=[{'name': 'ATRV'}, {'name': 'Wheel.4'}, {'name':
'Wheel.3'}, {'name': 'Wheel.2'}, {'name': 'Wheel.1'}])
print(bpy.context.selected_objects)
[bpy.data.objects["ATRV.001"], bpy.data.objects["Wheel.4"],
bpy.data.objects["Wheel.3"], bpy.data.objects["Wheel.2"],
bpy.data.objects["Wheel.1"]]

It would be usefull to have something like "autoselect=True" that we can
find in bpy.ops.wm.link_append.

Cheers,
