I have all the production files of an open-source movie in a folder. I open up a Blender file, say scene1.blend, and save a copy, say scene1_copy.blend, in another folder. This scene1_copy.blend, works perfectly, knowing where to find all those assets, etc.
Now I want to move all the production files to a new folder. I tried just moving them, but then my scene1_copy.blend cannot find all the production files, which is no surprise.
How can I let scene1_copy.blend know where to look for those production files?
