Yupp... knew I hadn't made myself clear smiles.   I can do all that but.... I am trying to save it into my library so that all I have to do is 'double click' on the 'mat' in pose and it will be changed. I can do it with clothing (and have even uploaded some freebies), but for some reason this isn't working and I am wondering if it's because I have added the 'material'. Now that I have made and saved the 'material', do I not try to add it in the .pz2.... but just add it after when I want to use it?
