I am making a project where I use materials from an external file.Both my files are present in a folder. I append them. While scripting, I specified the absolute path of the file. But if I copy the folder with both project and materials file into another system. Then appending them shows an error because the path that I specified is no longer the materials path. So, can anyone help me out so that I can set up the path such that it imports material from within the folder that contains these files?
