I have started playing around with externally linked groups. This is a great way to develope scenes using a distributed architechture approach. However, I have run into a snag. Everytime I try to edit the material of an externally linked object, I am denied access. It seems you can only edit the material in the original scene where the externally linked object resides.
Consider my scenario. I have a 2:38 video of flying pictures to sling around. Currently the pictures are just an image on a plane. So I create a plane object in one file and give it a group name.
I open up another blender scene and link in (not append) the group which is just the plane. I dupligroup the plane to an empty and viola I have my externally linked plane in my scene. This is great because I may want to add a frame later on or even make it a softbody later. Whatever I choose to do to the externally linked plane it will effect every instance in my animation. Very powerful indeed.
Now for my woeful let down. I need to actually assign a different image to each plane I bring in. But Blender will not let me do that to an externally linked group.
Is there a way around that? I only want to link to the mesh, not the material. Can I bring the material local, but leave the mesh external?
I hope this makes sense to someone…
