S4S will create a folder in the same location as your package that has all the various texture files associated with your package in PNG format. Step 2: Once you have your swatches in place, press CTRL+SHIFT+C (the same command to open the cheats window in TS4) and type studio.exportall
Step 1: Open S4S and ready your package by creating your swatches (the easiest way to do this is to load a colour palette you’ve already prepared using Tools > Color Palette but you can do it manually if you need to) They make it a lot, lot easier to get your files in and out of the program (which is especially welcome when making walls and/or anything with a lot of swatches).
I’m minded not everyone may know about the batch export and import cheats in Sims 4 Studio.
