I am new to Peggy Zone and I am looking to learn to create custom contents because I really like to see Burberry and Louis Vuitton's items in TS3. I tried to download several patterns available on The Exchange website but they are not shown in game for some reason so I started to think of making my own patterns and custom contents (especially when I saw people creating their own pretty patterns). Hence I was browsing through the TS3 forum and came across Peggy Zone. I checked out the Tutorial Section but have no idea about the programs people use the most. So I would like to know what program do you all use to create all the beautiful custom contents so I can start creating and sharing my contents?
I have PS and other 3D programs but the major problem for me right now is how am I going to convert what I've created into .package file type so TS3 will recognize it?
