So I suggest you creators to use this UV template below. Because I see other templates shared on S4S forum like this and this. Then I thought maybe not every creators use same UV template as I do (or maybe they use but don’t bother to follow that template duh). If other creator, for example Creator A put their top UV on that little space and Creator B also mapped their skirt UV on there, texture overlapping problem will happens. This happened is because they put their mesh UV into that extra space I mention above. Like sometimes you will spot some weird texture on your outfit when you put certain top/bottom on your sims. The reason I write this message is because I found out some clothes that I downloaded from other creators, their clothes texture overlap with my clothes or even with their own other clothes. That space locates at the bottom of the arms. You will also know Sims 4 UV template has an small rectangular space as an extra for us to put our mesh UV too. As you know sims 4 UV template have very limited space so we always have to try our best to fit our mesh UV into it.
