Just ran a skatter on a surface and had only 2 objects (circles) populate, whereas if I manually position a grid of the objects over the surface, I can fit 7. That’s a pretty impressive disparity.
You can obviously change the density by lowering the “Spacing” values. But you probably already know that.
On top of that, there are “Shift” values that allow you to move the origin of the grid. It might help fit more objects on your host, depending on its shape.
The “Rotation” may also help.
