I work a lot with linked data and library objects or linked collections.
Is it possible to send values or variables between the different hierachical structures ?
So for example:
- SCENEFILE (var = 1234)
- ---> Linked object 1 (pass_index + var)
- ---> Linked object 2 (locationX + var)
or to add a bit and be more precise:
If I have a gamma node for example inside a material in a linked Collection, how do I access these gamma node value and Control it from the MainStage ? can i use a Driver from the MainStage to Control these values inside linked objects?
OK - > I got a step further and can control a value inside the linked Object.
linked objects can accessed via python as seen here in this Video
https://www.youtube.com/watch?v=5M6cdhn4YCE
so
bpy.data.objects['Name_of_the_linked_obj'].pass_index
gives Access to the pass_index for example and can be set via python
bpy.data.objects['Name_of_the_linked_obj'].pass_index = 3
this is nice but not very comfortable or usable.
Now it would be great to have a way to control this datapath via Driver or Custom Property from the mainfile.
as you can see in the picture we can access this property in a Driver.
so I created a controller object that can drive this value and can override it.
but the data in the linked object does not change and
bpy.data.objects['Name_of_the_linked_obj'].pass_index = 3
is not evaluated
but when I use
bpy.data.objects['myCube'].pass_index = bpy.data.objects['Controller']['my_new_index']
it works immediatly...
here is the setup image
