How do I reload a linked blender file?
I linked a
.blend file into another. After I update the linked file (say change the material color), how do I make the project I imported it into update?
There is also a great addon, written by Pablo Vazquez, called "Amaranth", which include a little feature (among others) : "Save and reload"
http://www.pablovazquez.org/amaranth/ (see the bottom of this page)
After installing it, you'll just have to hit CTRL SHIFT W (or go into File menu), to save and reload the current file. It should update all linked data as well.
Another great add-on that will allow you to easily edit your linked object from your scene and then switch back to your scene containing the linked item is called Edit Linked Library.
Edit Linked Library is simple to use and you can find usage instructions at http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Object/Edit_Linked_Library
