white mesh means no textures, you don't need any .x only the DDS files, you can easily get them in the texture/char folder of Ran PH client, or search the forum someone shared it before
Are you sure you got the right textures?
To find out what the right textures are, open the cps file with hex editor or with my editor and check what textures they call, then make sure you have those textures in the texture/char folder
