Chaos Scatter Edge Trimming Playground!
romullus:
I think it's the case of you misunderstanding how this feature works. It removes any mesh element that are placed outside of scattered area*. It will not remove anything if your instances consist of single element, like box, or teapot in your examples.
* i'm not exactly sure how the scatter determines when element is considered to be outside of scattered area. It looks that decision is taken not by dimensions of element bounding box, but rather by the placement of its base, which IMHO is very nice feature!

Bug report - edge trimming isn't working if plugged through Corona select texmap.
romullus:
Here's quick comparison between spline areas, edge trimming and slicer. I think some people expected edge trimming to work like slicer. Personally i find current behaviour much more natural and realistic, but it seems that there are some issues with edge detection precision, which i'm sure will be fixed by the devs in future builds.

Works with grass downloaded from cosmos, but not with geometry create by myself (cube).

A single box is a single element. Try with a clump of grass consisting of many elements.
It considers the pivot of the element, not its bounding box. So any element whose pivot is outside of the defined area will disappear (grass blade growing on a plane will be visible, grass blade growing outside of plane will disappear). We may consider the bounding box or or other methods of trimming in future versions too.

Please make it optional, in many cases pivot point detection makes more sense than bounding box detection.
