Turning on the Edge Trimming function deletes all grass strands that are outside of the Target Object, creating a clean line, imitating that the grass has been professionally cut.

Slope Limitation

...

Section
Column
width55%

Slope Limitation limits scattering only to 'slopes' at certain angles. It can be used to create realistic spread of trees on curved surfaces, for instance. The lower the Angle range is set, the smaller the angle at which scattering stops.

Up Axis – The angles are measured either between the Local Up Axis and the surface normal, or the World Up Axis and the surface normal. You can select which up normal to use:

Local – When enabled, the Slope Limitation is measured according to the up vector of each individual Targets object.
World – When enabled, the Slope Limitation is measured according to the world Y-axis up vector for all Targets objects in the scene.

See the Slope Limitation Up Axis example for more information.

Min Angle/Max Angle – Defines a range of angles to which the scattering is limited. Instances outside of this range get filtered out. See the Min/Max Angle example below for more information.

The Local and World Slope Limitations determine the up-vector. The Local option uses the normals of the Target object; the World option uses the Y-axis of the scene. In this example, the Min/Max Angle is set to 0.0°-45.0°.

Setting the Max Altitude to 5000.000 cm (500m) limits the scattered trees to that height.

Falloff Curve

Section
Column

The Falloff Curve specifies the density of the scattered objects depending on their altitude.

Lowering the point on the left side of the curve results in lowering the density of the objects closer to the minimum altitude range. Lowering the point on the right side of the curve results in lowering the density of the objects close to the maximum altitude range.

The Expand button opens the Falloff Curve in a separate window.
