Hi,
Did you notice the blend of the 2001 car at the end of the test...
I simply build a mod (25 and counting) with the right cars (LOD and TEX files) and make sure there are no older files in the mod...
Right... Now to the white cars issue..
Really beats me as well as to what you have shown... LOD files may have got mixed up as well...
I to had such issues but they were actually related to Hi-res mod running in medium or low graphics in GP4.. The White cars effect and vice versa...
Try to take a look inside the cars.wad file and only leave the 2011 hi-res TEX files.. Delete low-res and other 2001 TEX files and check the results.. Make sure you are using the right LOD.. Make sure no two teams have the same LOD name...
Hope it helps..
