I hope I can explain correctly what is my problem.
I'm making a custom bed and as you know, each swatch has 2 textures (frame and mattress). I have 4 textures for the frame and 9 textures for the mattress. It does 36 swatches.
I would like to not dupplicate any texture in my package to be the lighter as possible. But I'm not able to do it with S4S or TSRW.
