No need for 3DsimEd to do that, just create a track skin in CM and you can override (replace) any textures used with whatever you want. Giant cats, even.
(it's been done before... )
I know that, but I don't know how to get the original textures to edit other than using the 3dSimED program. It puts all the textures in a temp folder so it's easy to edit the ones I want to edit. If there is another way to extract the textures from a .kn5 file, i'm all ears cause i'm kind of new to this stuff.
