Haha, okay thanks! Now I just have the massive task of trying to understand something I don't know how to do even though I am following your tutorial (which is very detailed and understandable)! What I gather from the tutorial is that I now have to change the data on the Excel document to the numbers of each of the tiles in my tileset which was created in Sphere as per the tutorial? This ended up in giving me a tileset with 440 tiles and no duplicates.
I see how your tutorial works now, you take the tile number convert and place in the excel file what I have to do is not particularly hard but is very long-winded. Converting 440 tiles from HEX to Decimal, DAMN! xDD
