The primary goal of extreme sliders is . In the unmodded game, the "Push and Pull" system has hard-coded stops to prevent visual glitches.

: A known and unavoidable side-effect of extreme sliders is that when you push a slider to an extreme, another part of the body might shrink. For example, pushing the waist slider to its maximum might cause the head and upper body to shrink, or extending the hip slider could make the legs and feet appear smaller. This is a core game limitation that most modders cannot bypass.
