I have Found that placing Data folder to data folder then overwriting Doesn't always work. The way that I do it is by opening each folder under the data folder and copy all the files under each Folder and pasting the files into each same named folder in the C:/Program Files/Lionhead Studios Ltd/The Movies/Data/(Files from Meshes Folder into Folders Meshes, Files from Setdressing into Setdressing Folder..etc)
This usually Works for all Props, Costumes, sets, Backdrops..etc
If you have Trouble look at propblueprint.ini file some times
the data is messedup here.
Catagory
