Or, skin details that only cover the sim's body or sim's face – it would be great to mix and match with these but if you can only have one or the other, it's not very useful. Now certain otherwise wonderful non full body skin details are practically unusable because they reveal the pudding-faced Maxis skin that I don't wish to see in my game. In the ideal situation, I'd pick one 'skin detail' that is in fact a full body skin, and when required for additional variance, add 1-4 non full body skin details on top of that one. Why does this happen and how can I prevent it? If the sim was only wearing one skin detail and activating another one would replace that one only, I would guess that they might be occupying exactly the same sorting number, but since this isn't the case, I'm not sure anymore. Some of the CC there is layerable, but some skin details cause all other currently activated skin details to get removed if selected. There is one more thing puzzling me though – I have a lot of content in the 'skin details' category.
