As I have been making more and more overlays, I noticed differences in how transparent images would overlay on the sim, based on which skin detail I started with. Since, I prefer the look of one, I narrowed it down and found the easy way to play with how the transparency blends. To do this, I will assume you have a basic knowledge of S4S, and how to make a transparent overlay with a 2D editor.
I will use my Defined Hand Overlay, which is still not at its peak of perfection in these pics (I have to clarify that!) Here is a look at my Overlay in S4S, so you can see what my original image looks like:
The area we will be editing is the "CompositionMethod," in the warehouse.
Go to the CAS part you want to adjust, and in warehouse scroll down to “CompositionMethod.” Depending on what you are starting with you will likely either see a 0, 1, or 3.
Here is an example of how my Defined Hand Overlay changed with using different numbers. In my opinion, “3” is the best for doing overlays/skin detail. 3 subdues the whites the most, which works well when trying to do an overlay for all skin tones, since these changes shown above may not be so noticeable on the lighter skin tones. 0 can work well to make the whites pop a bit more, making it look a bit shinier. Opening clothing items, it appears that the EA default is to use 0. I have not changed the number when doing clothing, so I’m not sure if that would give you the desired effect, but it may be fun to play with. “None” in the picture above is just the regular EA skin, with no overlay at all.
I also tried using numbers above 4, but it seems 4 is the max, and anything higher will just cause the item to not show up.
