How do I .. In chaos scatter

[MetricaVisuals]

Hi, im trying to do some simple scatter using chaos scatter.

1. First when i make an spline scatter, where can i specify a surface for it to stick to??
2. How can i scatter an empty object ? In forest i just create an empty object and that way i can have an scatter that has some gaps, like its not filling all the spaces (its really handy, trust me...)
In corona scatter if i create a box and turn it not renderable the scatter will render it... If i create a dummy it will not work..

Thx in advance !

1. In spline mode Chaos scatter distributes objects on spline, not on surface. If you want that scattered objects would also follow elevation of some surface, you need to conform guide spline to that surface first.

2. You can create simple box and assign empty Corona rayswitch material to it. The scatter will treat the box like regular object, but it won't be visible in render.
