Just a python script which moves all texture assets in a maya scene that are being used from a megascans downloads folder to the sourceimages folder, as well as changing the file paths so it links to the new directory automatically
Base of the code comes from this thread https://forums.autodesk.com/t5/maya-forum/easy-way-to-relocate-textures-to-current-project/td-p/6542378, however I've changed it to automatically use project folders instead of dumping everything into a manually defined target folder, as well as other improvements that I can't remember.
