Re: S4S Can't Recolor/Export or Import Texture
I'm not sure at all what you have happening but you would probably be better served by asking at the S4S site. That said, here's a guess.
My guess is that the 3rd chandelier may be getting its colors from one of the other two. So, after you finish adding the recolors to all of them, take a look at them in game to see what they look like. Since the only thing really different about them is the size, they probably have the same mapping which makes it easy for the textures to be on one object but used by another similar item.
Depending on if you made your recolors as standalone objects or meant to add swatches to the base game objects or an override, the 3rd chandelier might not show up at all or with the red or black checkerboard pattern.
Having an object get it's recolors from another similar item is an old trick that CC makers used to use back in the TS2 days since it could reduce file sizes. It's not much used with TS4 CC very much that I have found. I have only seen it done with a few CAS items.
Hope this helps.
