I am looking for a way to use relative paths in Blender to link to external image, movie, etc... files. I assemble all of my .blend files on my MacBook (OS X Yosemite) and link to the images I've selected by connecting my Finder to a downstairs headless Xubuntu server, through which Blender can then create an absolute path. I then render using this server. However, I have been looking for a way around linking Finder and creating an absolute path, as I must be at my house to connect Finder. I've read that if I use a relative path (//file1), as opposed to an absolute path (Users/.../file1), I should be able to easily send an entire folder, assembled locally on my laptop, to the server, but I haven't been able to get this to work.
In an attempt to create relative paths, I remapped all of the paths in one of my existing .blend files to correspond to the same image textures locally in the folder on my computer where I store said .blend file. I then tried to use the File > External Data > Make All Paths Relative option, but all of my paths were still absolute. Any thoughts?
