+## Compare files with originals

+Sometimes it is useful to see what nadeo used, so you need the original files.

+You need TMValley_HD.zip or TMValley.zip and the Updated files e.g. for Valley,Stadium,Canyon...
+Unzip them at the destination of your choice.

 An alternative way to do these textures is to save all of them as 24bit tga files and import this tga files with the importer (instead of the dds ones), the nadeo importer will convert em into the right dds format. For files with alpha channel: They need to be 32bit tga with alpha saved!
 I recommend to do the dds files by your own
 
->>>>> You can work in tga and use the importer to create the dds (see first post). You won't destroy your source with dds compression, and saves will be faster.
