Thank you for your swift reply,
Well it was, But being a neat Freak, i always reaarrange my folders in my private collection folders, thus removing the .mat to my material libraries and the maps to my maps collection and the max to my max collection folders.
Guess this is why it was not seing it.
It is working now and I can see the previews in the Catalog, but when I choose a palm it does not apply it to the scene, guess because I have changed the folder name, or it does not matter?? what should the folder name be?
Thank you very much
