"As someone who often has to switch between workstations when working on a project, the file path of the textures is very important. No matter how many times I save the files to relative, Maya always, ALWAYS, sets them to global. This is particularly annoying in the lighting/rendering stage, when I often have to link the files again to the project folder. The path SHOULD be relative if it's saved as relative.
There is a script to quickly rename all the files in a scene called "Clean Texture Paths" from Lightcraft, but this is only a temp solution to a problem that shouldn't happen in the first place.
Please, please, make file paths relative to the project folder, not the entire drive."
