Using S4S to create a mod that shd show up in CAS DEMO

but it isn't.    My item is a recolor of a basegame item, and I have gone into the warehouse checking each texture to show up in CAS Demo mode, but none of the recolors are showing up.

1.  The saved mod is in the CAS Demo mods folder.
2.  I want to use the CAS Demo for a quick view of how the recolor will look - so I can eliminate searching, my game loading, blahblahblah  LOL....


can anyone assist?
